CartridgeCorner–If the the Rimfire book you are asking about is the “Rimfire Headstamp Guide”, contact George Kass at firstname.lastname@example.org. He still has the original 9 sections (50 headstamps per section) available at $10.00 per section. However the 4 pages shown by Otto are not included in the original publication but have been added later using the same format.
Also, don’t think that just because you have missing numbers in your pages that you are actually missing pages. I was the co-author of the RHG and what happened was that George and I original made crude drawings of every headstamp we knew existed in the late 1970’s and assigned numbers to them in sequence. However, before we would publish a page for the RHG we needed positive proof in the form of a box or a catalog for a headstamp. So, we might have proof for say D-8, D-9 & D-11, but not D-10. Thus the pages in the RHG skip D-10. Send me an email if you want a copy of all the original drawings showing all the headstamps and the numbers assigned to them. Note: this list does NOT include any ID’s.
