Nice score Andy52. Was the seller running a 2/3 off regular price sale ?
I like it when the manufacturers mark their holsters with easily decipherable letters and numbers. It's pretty easy to tell that one was for a 6" K frame, and the LBS code means Laced, Basketweave and Sight protector. The V shaped stitching on the upper leading edge should be holding a leather welt on the inside of the throat to protect the rear adjustable sight. Someone wanted a deluxe holster for their prized K-22 or K-38 back about a half century ago.
