The Colt Pocket Positive revolver or the Folsom Audley holster for it? The Colt was made in the 1930s and the holster maybe a bit earlier. The Colt only has a bit of bluing wear at the muzzle and a couple of other small spots from being in a holster. The grip panels are real stag, but not factory Colt. The Colt Pocket Positives were chambered for the .32 Colt New Police round which is identical to the S&W 32 Long cartridge. This was the smallest double action/swing out cylinder revolver that Colt made. They came with 2 1/2" to 6" barrels and were either blued or nickled.
The Folsom Audley holster looks to be unused. The Audley holster has a built in spring catch to hold the gun in the holster. To draw the weapon, the trigger finger automatically presses the spring to release the gun. There were about a dozen or so variations of the Folsom/Audley holsters made for revolvers and pistols.
