Not much leather for me - kydex for the EDC. For dad's old .38 Colt, I have some current nylon rigs (hip and shoulder), as well as dad's Korea-era (original!) USN-embossed shoulder rig, complete with bullet loops and a nice green coating on the hardware from being at sea so long back in the '50s. It's "non-original" though - dad was with Intel, and according to him he was assigned to a squad of SAS at one point, who were blowing bridges and dad went along as USN 'eyes' to verify objectives and results. One of them took his holster one night, and dyed it black because "that brown leather is going to get one of us killed because it doesn't blend in". Not sure if there's embellishment in there anywhere, but...I trust dad, he wasn't one to make stuff up.
I won't clean it or restore it.
