Oooo...I like the brown one!!!
Back in the 50's, I had a two-gun holster set for SAA's that I put two Mattel "Fanner 50's" in...They were made from a WW II bomber jacket; sheepskin w/the 'fur' on the inside of the holsters...Like yours...Laced up the edges...With 'drop hanger' belt loops made from sheepskin/jacket, too...
I think they were locally made...And I don't recall very well, but I think my dad got them from Card's Military Surplus...He got a lot of stuff from them...Like a couple of Hallicrafter military radios [aircraft models], that got all freqs...Police, military, airline...He was a 'ham'
[W2JNR] and used to talk to other hams frequently...Our basement wall was plastered with ham postcards...and he had a couple wads of his that he sent out...
Cards had all kinds of GI stuff...Clothes, equipment, even vehicles...
