2. It has a preliminary proof mark, then an F with an arrow(?) pointing down to an R with what looks like a crown over it, then the traditional black powder proof mark.
About the marks. The "arrow" is a perron, proof of the breeching system. The R with crown is a rifled barrel over 8mm used since 1897. The F could be a date code or the inspector's mark. Either would date the proof to about 1927. The 9.2 is the bore in mm. http://damascus-barrels.com/Belgian_All_Proofmarks.htmlPieper made a lot of proprietary cartridges. This could well have been chambered for an obsolete Pieper round for which there is no brass. Send it back. Mike posted some nice guns. I like this one that he posted: http://www.gunsinternational.com/detail.cfm?id=100057670&string=act=advPete

400 Nitro Express:
Thanks for the correction. I knew the pressure for the Cordite round was low, but didn't realize the pressure was around 31k psi.
Kind Regards,

Raimey sent me pictures of the gun. It dates 1898-1924. No Greener cross bolt.

Jerry:
The "17 tons" is the long out of use bolt thrust standard derived in base-crusher guns. It isn't chamber pressure. Current standard for the Flanged Magnum's chamber pressure is 3250 BAR/47,137 PSI. Still way over the top. The rimless Magnum is 62,000.
Also, Taylor had his data wrong on this one. Original standard for the .375 Flanged Magnum was 18 tons, not 17.

400, Taylor listed the heavy bullet loads at 18 tons, not the 235 gr. He did have a ? mark in his book on that load.
Thanks for the education on how older guns measured pressure.

I found out the rifle was originally a 9.5 x 57 and the salesman (I haven't talked to the owner) thought it had a nitro proof on it, could I be missing it?

Well, at least 9.5mm is nominally .375" diameter. I'd still slug the bore. If it was a 9.5X57, rechambering doesn't make sense, unless the chamber was ruined to begin with.

Once again on memory, which wasn't too good regarding 375 Nitro pressure, I recall that the 9.5X57 was a Mannlicher-Schoenauer or something of the like and was the same or all but the same as the 375 Rimless Nitro Express(I think I have some ammo).
Send it back if it has been altered.
Kind Regards,

Jerry it sounds like you really want to keep the gun. All of the responses have said send it back or don't shoot it. All that we can say is what we'd do if it was us. You have to make the decision. Good luck.
