I checked the Bucheimer charts and unless I missed one I need assistance in finding this holster that might be for a S&W model 19 2.5. It's a Bucheimer B.01.004.L.69P. It's black, lined and still in nice shape. I'll update with a couple photos shortly. Appreciate any help/guidance.

This probably doesn't help you, but I have a Bucheimer holster for the S&W K, 2 1/2", unlined, retention strap and strap around the body of the holster. Almost new. The only markings are: B3, Bucheimer "b logo", and "Perfect Fit" legend.
