Tamiya's old quad 20mm kit, although not quite up to today's Tamiya standards, is still the only option for this configuration on the market and with the addition of a photo etched set and some turned barrels can be made into quite the stunner.  Eduard's new set contains 2 large etched sheets. 

Main detail parts include parts for the gun base, seat backs, gun sights, ammo mounts, new gun shields and parts to detail the trailer, including new mudflaps and light mounts
