I think they were all 57's according to myth and leo lore.....
A 58 would be a find. Wasn't aware they made such a critter....never seen one.
Wonder of the 454 Casull can be chambered and used in a 25 ? Let a user have 45 Colt or the 454 for big and bad ???
I've seen a 58 at Petersons. It looks sorta like a Model 10 on steroids, with matte blue like a 28.
