Another question. In the Reisch book, it shows IBM stocks have only the ordnance wheel on the right side, and three small letters or so in the sling well. Am I reading that correct. In my stash at the shop, I have a really nice carbine stock that I know has only the ordnance wheel. Not sure about the letters in the sling well, as its been a long time since I looked at it. When I go back to work Wednesday, I'll check it.
