The original prototype for the Domke bag was produced for him by Smith (in Chicago?) who made canvas tents for circuses.
They were sold under the Smith name by Ken Hansen, and I was lucky enough to get a couple, the New Yorker and New Yorker, Jr.
The New Yorker was taken in a home burglary, but thank Gawd I still have the Jr. It is the most perfect bag I could imagine, first for Leicas, DSLRs, and finally for Digital (both Canon SLRs and tiny little Sony RX100s.)
Oh, it is a wonderful bag, and saying that about a piece of photo equipment nearly 50 years old puts it in league with the original Leica, and Nikon SLR.
