From the estate of renowned armorist Verne Crofoot is a BT Crump Model 600 service holster. Well used with plenty of edge loss but no damage to speak of. Snaps work as intended and the stitching is complete and tight. I do not know exactly which revolver this holster was made for but the outline suggests a four inch barrel in .38 caliber. These were made for mostly the police during mid century. Please make sure this holster fits your need before purchasing.
