Not really. 9 out of 10 conehammer stocks are numbered on attaching iron. Only early 3-digit ones were numbered on hinge. For low 4-digit conehammer 1xxx, or, Turkish,,, I have never seen one coming with matching stock. I bet they were numbered on attaching iron too. When serial reach 2xxx, the number definitely should be on attaching iron.I believe Conehammer stocks are numbered on the hindge.
