Hi everyone! Thanks for the excellent information that you all have contributed to this thread. I just measured the cartridge box opening on my small ring action and it measures exacty 3.270" (83.058 mm) Very similar to the action shown in the top/upper position in the two posted photos. So as I read the thread, I understand that the 9,3 x 62 Conversion on a small ring action is possible with out too much hassle or work? (Please confirm)

A bit more info on the rifle. According to original proof info (2,4g G.M.B ST. m. G.) equates to 8x 57J (.318 bore). Mauser S/N is 1125 and Sauer S/N is 89057. Double Set Triggers. Looking at the action with the stock removed, I see no indication that the action was ever case colored, as seen on some Sauer-Mausers. Rifle has Sauer type single foot claw mounts numbered 490 (likely to match orginal scope which is long gone) Barrel is octogon to round with one fixed rear sight and one flip up sight. Barrel, as noted in begining of this thread is currently 7x57 proofed in "532" (May 1932) Barrel has the "BUG" proofs and action has the "BU" proofs.

On another note. Anyone have a set of single foot claw rings that they would like to find a home for????

My intent with the rifle is to re-bore and chamber, case color frame and small parts and restock in Turkish walnut; A piece which I already have. I appreciate all of your help and insight on my project and from time to time may post photos as the project proceeds as time and budget allows. JeffS.
