Ian, There has been discussion before about the possible maker for this A2. There was an order placed on 13th June 1944 for A2 jackets from two makers, one being Perry Sportswear for 25,000 A2s and the other being Dubow. These jackets were replacements for earlier issued A2s. We know that the two previous Perry contracts were from 1941-2 and there are no other named Perry contract A2s after this date. My guess is that this no name maker jacket was made by Perry and is from the June 1944 order. As you say Ian it does have many of the features associated with this maker, including the collar stand, Conmar zip, typical Perry-shaped pocket flaps etc.. John Chapman may not have been aware of the existence of 13th June document when he compiled his CD. There are no other late War A2 contracts which resemble Perry A2s. It is also worth pointing out that the Dubow order from June 1944 is 1755 and this no name one is 1756, suggesting the orders were placed at the same time and if you link it with the June document Perry is the most likely maker. Although this evidence about Perry being the maker of this no name A2 is not conclusive it is nevertheless fairly compelling IMO..
