That is actually a left handed flap holster. The belt end that is shown is on the left handed end of the belt, the buckle was normally on the right handed end.
Clark, thanks for your observations. The resolution of that black and white image is not great. I have seen other, more recent photos of this pistol and accoutrements with better resolution, but I am unable to share them on the forum.
If the flap holster in the photo is worn on a belt in the customary fashion on the shooter's
left side, the pistol butt would be pointed forward, for a right hand cross draw, or a rather awkward left hand "twist draw." The same holster on a belt on the shooter's
right side would position the pistol with the butt to the rear, for a right hand "straight draw." To me, that would be a right-handed holster. Your terminology may be different.
Regarding the belt, I believe it is a recycled military belt. The brass fitting you see on the end of the belt, with the rectangular hole, is indeed the "receiver" (for lack of a better word) for the hook on a military belt plate, or "two piece buckle." Normally, the other end of the belt would be doubled over a bar on the belt plate, and the very tip of that end of the belt would have an adjustment hook riveted on, to engage holes punched in the leather. You don't have the benefit of seeing the other end of the belt, which was clearly visible in the more recent images I was able to view, but I can tell you the belt plate is missing, as is the leather keeper. The other end of this belt has the brass adjustment hook still riveted on, and the belt is opened up to its full length. If worn as a waist belt, this would only fit a man of considerable girth, and it leads me to believe Mr. Plott
may have slung the belt over his shoulder to carry the pistol in its holster.
It is an interesting outfit, in any event.
Thanks for your comments.
