The Quest for Accuraccy
by Thomas L. Jentz and Hilary L. Doyle
The highest possible accuracy is the standard set by the Panzer Tracts
team. This goal can only be achieved by researching all available original
material on a subject before each book is written. A high degree of accuracy
can't be achieved by simply reading the original works by Walter J. Spielberger
or compiling notes from hundreds of other books that reuse the material
that he published or make assumptions based on photographs. A lifetime's
effort must be expended in gathering an extensive database of original
source material.
During the past 35 years, we have collected data, reports, surveys, manufacturer's
drawings, and photographs from many sources, including these major establishments
(and the search still goes on):

visits to search through thousands of rolls of microfilm, boxes of records,
and boxes of photographs)

all of the original records and drawings on Panzers and Panzer units
not on microfilm at the National Archives)

19 private collections of vehicles and monuments throughout
Europe.
We have been fortunate to have the support of some fellow enthusiasts
who have surveyed vehicles in museums and private collections that so
far have been inaccessible to us.
Private collections
Walter J. Spielberger Collection. In addition to unlimited access
to Walter's collection over the past 35 years, we co-authored Walter's
last four books and prepared the scale drawings for his complete series.
Prior to donating the bulk of his collection to the Panzer Museum in
Munster, Walter gave us whatever original documents and photographs
we required.
Jarrett Collection in Carlisle, USA
Icks Collection in the Patton Museum, USA
Col. Obry Collection in Saumur, France
Fritz Wiener Collection, Vienna, Austria, via Spielberger
Oberst Icken Collection, Germany, via Spielberger
Becker Collection, Germany, via Spielberger
Charlie Yust Collection, Bel Air, MD
Fellow enthusiasts have shared original documents and photographs over
the years. Among them are: Peter Chamberlain, Bill Auerbach, Dr. Werner
Regenberg, Karlheinz Muench, Marcus Jaugitz, Wolfgang Schneider, Steven
Zaloga and Thomas Andersen.
The Jentz/Doyle collection is now one of the most comprehensive private
archives in the world. The collection contains copies of tens of thousands
of original documents, the largest private collection of manufacturer's
drawings in the world, thousands of photographs of surviving vehicles,
prints of thousands of original wartime photographs, hundreds of manuals,
and tens of thousands Fahrgestell Nummern.
We are doing our homework! This is why the Panzer Tracts authors goal
is to produce the highest quality books possible - with new data, new
drawings, new photographs, and new information! And best of all, you
can be assured that they are based solely on the content of original
documents written during the war by those who actually took part in
the design projects, production, distribution, and use of the Panzers
in combat. They are totally free from the thousands of mistakes, misinterpretations,
guesses, and tall tales present in hundreds of other published books.
To reach the Panzer Tracts standard of quality in our new drawings,
we cross-check measurements of surviving vehicles with the manufacturer's
specifications and available photographs. An accurate record of the
monthly production by each assembly plant and Fgst.Nr. series assigned
to each was compiled as an aid in placing identified modifications in
chronological sequence. We always search for the Fgst.Nr. (and other
identifying numbers and manufacturer's code letters) of each Panzer
so that we know where and when it was assembled.
It takes over 30 hours on-site to accurately measure each existing
vehicle in detail. It takes several visits to ensure all the necessary
details are accurately recorded. We measure as many vehicles from a
series as possible. How else could we discover that the gun mantlet
of a Panther Ausf.D is narrower than that of an Ausf.A? We take hundreds
of detailed photographs of each Panzer for aid in drawing. Then comes
the hard part, requiring skill, tenacity, and patience to spend the
hundreds of hours needed to create the final product - an accurate scale
drawing. We believe in creating a product that we can be proud of and
spend the time to do the job right - as can be easily observed by comparing
our product with any others.
These scale prints are not created by scanning the distorted drawings
from manuals or copying the original large-scale drawings - for the
simple reason that these originals are not as-built drawings. Most of
the original drawings are overviews of a vehicle made early in the project
prior to the creation of the thousands of detail drawings actually needed
to produce it. These were rarely corrected to reflect changes needed
to produce the parts and do not represent the completed product. Compare
the original drawing from a manual of the Pz.Kpfw.IV Ausf.D with the
as-built drawing of a Pz.Kpfw.IV Ausf.D completed
by Hilary. Scale drawings created by Hilary L. Doyle are usually the
first accurate record of a Panzer as it was actually produced.
In addition, every Panzer
in a museum or private collection has parts missing, and many have inaccurate
replacement parts added during restoration attempts. We conduct the
detailed research necessary to recreate accurate scale prints with the
same details as when the Panzer originally left the factory. If we can't
find what an original part looked like because the records or photographs
didn't survive (such as some details inside the Ostwind turret in Panzer
Tracts 12) we now leave it off - or tell you exactly when a reconstruction
has been attempted (such as the rear deck of the VK 30.01 and VK 36.01
in Panzer Tracts 6).
With regard to historical accuracy, it isn't enough just to collect
original sources. One must know the language in which the records were
originally written and have the technical background needed to understand
them. The temptation must be resisted to fill in missing information
where the original records have not survived. This lesson was learned
by us long ago (but not before the Encyclopedia was printed). Anytime
"logic" was used to fill a gap in the record, invariably this
"logical answer" was proven to be false when original records
were found. It is impossible to guess the right answers when data are
missing. The designers came from a WWI perspective and were forced by
dire circumstances into decisions that we can't visualize - we know
where they went, but can't imagine how they got there. Sufficient time
has to be spent digging out the surviving original documents before
a book is attempted. After exhausting all the trails, it is also necessary
to be disciplined enough to leave the missing gaps where original data
have not survived.
Infrequently, conflicting data appear in the original records and must
be properly sorted out. Technical data can usually be resolved by examining
a surviving Panzer and finding the original designer's reports. Historical
data on unit strengths and composition can usually be resolved by performing
a material balance and comparing reports at all levels from issue to
disposal. Other conflicting data and statements can usually be resolved
when a comparison is made between records created at the time by those
not directly involved with those who were. For example, the postwar
report stating that Ford and GM did not produce Panzers for Germany
because of their affiliation with the U.S. - is false. It was made by
an individual in a responsible position at the end of the war - but
he was not in office when the actual decision was made to reject Ford-style
assembly line methods as incompatible with necessary design changes.
Most of the immediate postwar interrogation reports are full of this
type of error - the right questions asked to the wrong people.
And now it is 56 years later. When personnel involved with the projects
and campaigns were interrogated and wrote reports (without access to
their original documents) directly after the war couldn't produce reliable
information, what chance is there of obtaining any useful information
by questioning veterans today? Should information from documents created
at the time by the participants be replaced by stories told by veterans
fifty years later? While war stories may be entertaining, they are not
a reliable source of accurate information. For example, schwere Panzer-Abteilung
501 in Tunisia in late 1942/early 1943 was outfitted and organized in
accordance with the applicable K.St.N.s for the period as shown below
(copyright Thomas L.Jentz from Germany's Tiger Tanks - Tiger I &
II Combat Tactics. As recorded in January 1943, the tactical numbers
were stenciled on the tank turrets of the 1.Kompanie as follows:
Tigers Pz.Kpfw.III
Kp.Tr. 11 12 & 13
1.Zug 111 & 112 113 & 114
2.Zug 121 & 122 123 & 124
3.Zug 131 & 132 133 & 134
4.Zug 141 & 142 143 & 144
As seen in this well-known photo (No.1070/84 reproduced with permission
from the Tank Museum), prior to capture this Pz.Kpfw.III Ausf.N (tactical
number 242) was with the 2.Kompanie/schwere Panzer-Abteilung 501. So
why would anyone interested in accuracy publish a diagram showing the
company commander's Tiger numbered "100",
Pz.Kpfw.III Ausf.M in the 1.Kompanie instead of Pz.Kpfw.III Ausf.N,
no Pz.Kpfw.IIIs in the 2.Kompanie, and the second Tiger in each Zug
numbered 212, 222, 232, and 242?
st history". It simply eliminates previous mistakes in order to
create an "original" accurate record. But it takes time to
do the job right. Did anyone ever wonder why Panzer Tracts are not released
in numerical order? We are still constantly making research trips to
find new information. We also constantly revisit previously reviewed
material to discover new facts as our subject knowledge improves. We
don't put our names on the cover until the facts are in and accurate
drawings completed.
