And... eclectic remember.
Got revolvers in:
.455 Webley. A Webley MK VI. And since it was made in 1915... It's a first year production.
.45 Colt. A Colt SAA 7 1/2 barrel, 3rd Generation. made in 1978... Guess what?
.45 ACP. A S&W 1917, a commercial made in 1937.
.44-40. A Uberti SAA clone, 5 1/5 barrel.
.38 S&W. A Royal Enfield MK II made in 1934 and marked R.A.F.; A British Service S&W Victory, 5 inch barrel.
.357 Mag. A S&W 28-2, 6 inch barrel made in 1976; a Uberti Remington 1875 clone, 7 1/2 barrel; a Uberti SAA clone 4 3/4 barrel.
.38 SPL. A Colt OP 4 inch barrell made in 1937 (it found it's way to GB during the war. A lanyard ring was added, and the chambers were reamed out a smidge, so it can also fire .38 S&W; A S&W model 14 (can't remember dash what, but it was made in 1976).
.32 S&W long. A S&W 31-1, 3 inch barrel.
.22 WMR. A Uberti SAA clone, 5 1/5 barrel; A Dan Wesson, 6 inch barrel (solid rib, no underbarrel lug).
.22 LR. A S&W N frame, ex British Service .455 converted to .22; a stainless Uberti Stallion (same dimensions as the Ruger Single Six) with 4 3/4 barrel; a stainless Rossi(very similar to the S&W kit gun), 4 inch barrel.
Edit. Only counting cartridge firing revolvers here.
Edit2. Had to fix the Mark of the Webley. It's VI not a IV.
