As can be seen, it's in dark brown leather and marked "A. Davis & Co 1916" on the rear. A Mk VI fits it perfectly. The rear belt loop seems to have been cut about a bit, as does the holster flap which seems to have been reshaped. The "curve" of the flap close to the press-stud has been cut off and the front face of the "bucket" has also been cut so as to make it slightly deeper. The modifications are definitely almost as old as the holster as the edges are worn smooth and the colouring is exactly the same on the cut parts as the rest of the holster.
My questions are as follows:
1. Is it a standard issue holster?
2. I can understand cutting the flap and deepening the curve of the bucket opening as it makes it easier to grasp the revolver (is this something commonly seen?) but what is the purpose of cutting the rear belt-loop?
3. How is the holster supposed to have been worn? I presume the belt simply goes around the waist and the holster hangs on the hip "gunslinger" style? The belt loop is so stiff and tight I don't think a belt has ever been put through it with the weight of a revolver hanging off.
Anyway - hopefully it will be of some interest and perhaps someone can enlighten me on one or two of the questions?
