I just picked up this holster that came from a collector's estate. A handwritten note indicates it came with a Manhattan revolver. I laid a Colt Navy next to it and it seems like an exact fit (though I obviously didn't try to insert it!). The holster measures 13 1/8" from tip of the muzzle to the furthest point on the flap. There are no rivets or other metal fittings at all. It looks like there's some decorative tooling around the flap and in a couple of straight lines down the length of the holster. I'd love for it to be Confederate, of course, but I guess it could also be a private purchase officer's holster, or even civilian. Any information would be appreciated!
