Help IDing this holster?

[gunluvver]

I took a chance and picked up this holster hoping it would fit my 686-4 6". After giving it a good Neatsfoot oil soak, it fit the 686 like a glove, turning a darker saddle brown. I'm wondering how to decode the numbers stamped on the back. The 36 coincides with Buchmeiers listing fitting K frame and Model 19 6" barrels. Does this make it a Buchmeier? What does the 20 mean?

That’s a model 20 holster made by Smith & Wesson for a 6” K frame revolver as indicated by the size code 36. S&W was in the holster business in the 1970’s and into the ‘80’s.

After S&W spun off their holster operation , it became Gpuld & Goodrich
