New Bob Mernickle Freedom Arms Right Hand Holster. Not sure of exact barrel lengths Freedom Arms come in but a 4 3/4" Colt sticks out about 3/4". So, I would guess a 4" barrel of the larger frame FA. $55 delivered. 1st I'll take it followed by PM.
FYI: If it is a nearly perfect fit in terms of bulk, the holster is for 4.25-inch Model 97s. These revolver grip frames-cylinders are slightly smaller than those of a Colt SAA.
