Monte Carlo S 64 Hand Made in USA Right Hand Shooter Vertical Shoulder Holster. This is a vintage holster that came from the estate of a former LA vice detective. I know little about holsters so I'm going on the model number listed. I'm 5' 7" and it seemed a little short for me to wear. It measured approximately 20 - 22 inches from the top of my shoulder to the loop for your belt. I also believe it should have a strap that goes around the chest then hooks to the leather shoulder strap. I'm not sure of the gun it is used to carry. The holster appears to be for a revolver. The pocket for the gun measures approximately 2 - 3 inches wide and 6 inches deep. It also has the remains ( adhesive mark ) of the original price on the leather, see photo # 8. See all the photos for the best description of the holster with measurements.
