Up-dated pictures of 1940 DGL Irvin. I have owned this very rare jacket by the small London maker, DGL for around 7 years. It's currently up for sale so as a record here are some decent photos. It has all the features typical of this maker:-large collar rings, very narrow belt loops, an almost square ended collar and large rivets to secure the main zip. Originals from this maker are exceptionally rare especially in a desirable two panel construction in a decent size.
