5/14/20 - This is an unmarked holster for a Mauser model HSC or similar sized 7.65mm pistol. We first say HSc because the style / shape of the holster is one we often see paired with the Mauser HSc. There are no proof stamps or markings on this holster. All leather construction and style suggest WW2 era, but the condition is too clean for this to be that old, so best guess is a 1950s production.
