This is the second Knopf A2 that I have owned. The contract was awarded on 18th May 1942 and only 10,000 were made and for this reason originals are rarely seen these days. This CBI example is a size 44 has clearly seen plenty of action. The wristlets are replacements as is the NOS Talon zip. Originally it had a M-41 Talon, but this zip was defective. Some originals also had M-40 Conmar zippers fitted. The horse hide displays considerable grain. Like the Cable 27753, the maker used small nickel ring snaps made by Rau Fastener Co.
