This is more complicated than I usually get involved with but I’ll try.
I found the requested holster in a 1985-6 Bucheimer catalog that came in an Evaluators Ltd. inventory. A quick scan of the price list leads me to believe that 01 means it’s a holster. Belts are 02, clubs and saps are 03, cartridge and clip carriers are 04-the ‘80’s were a freewheeling time, you could call magazines clips- and onward. Luckily Bucheimer no longer made dog collars, just dog pads which are prefix 40.
The next number is the holster type, the holster requested is called the Accomodator. The last number is listed as the model number but is really the size code, 2 being the model number for “Will accommodate all popular 2”, 2 1/2” revolvers”. Model 4 will accommodate all popular 4” revolvers and all popular 4” & 5” autos, which of course is why they called this the Accommodator. The size codes for other holsters are more specific-1 for the Chiefs Special and like, 2 for the Detective Special, 3 for 2” K frame, etc. Now I’m tired and confused and of course my hip is hurting so that’s all for now. Bucheimer had 102 years to figure this system out according to the catalog cover “Since 1884”.
