Second the idea of checking on the ASSRA website with the hopes that Biggi will know about the rifle. I have seen several (maybe a dozen) bolt action near-Schuetzens with actions that resemble the 1871 Mauser in style, if not size. Never saw one that nice.
There are dozens of 9.3 or 9.5 rimmed Schutzen-type cartridges. To identify caliber completely, it may be necessary to look closely at the bolt face (flat, recessed or concave?) and to come up with theoretical measurements for rim diameter & rim thickness.
