I have come across an old, but in excellent condition, Roy's Leather Goods holster. It is marked "Roy's Leather Goods Magnolia, Ark.", which is stamped within a circle, and then the words "Patented .380 B-UP".
Does anyone know for what .380 this holster was made? The size and configuration seems to be correct for the Colt Mustang. Am I correct in that assumption?
Thanks

Would an AMT Back-up be too obvious a guess? Those are nice holsters by the way. I've managed to pick up a couple.
