From a 1973 catalog. The first page shows the code system used to describe a holster, the next 3 pages are a tri-fold out meant to be read across all 3 pages. There are probably size codes not shown but many popular handguns are listed. As Mr. Roy Jinks says, I hope this helps. ( when he says it, it always does help )
