Hello Green Man,
"DUH???".......My apologies. By "ground and renumbered receiver" I was referring ONLY to the location where it has been renumbered, not the entire receiver. However, after looking at the photos again, I mistakenly only scrolled high enough to see your photo, which I mistakenly assumed was just another photo of JaDub's rifle.
Having gone all the way up to the top of the thread, it's obvious that his receiver is untouched, in which case the barreled receiver of his rifle may have come from a wartime Bulgarian order filled from work in progress at Steyr. The top of the barrel is clean which confirms that it was never accepted by the KuK.
It is my understanding that there was some wartime production that was diverted to Bulgaria which were supplied without the typical coat-of-arms on the receiver or siderail date. His rifle clearly is marked with the Bulgarian rampant lion on the right side of the barrel and receiver, minus however the other typical markings, but with an original atypical serial number.
Since Bulgaria was the only other country using the M95 during WWI, other than captured weapons, this is my best guess as to the origins of this rifle.
Regarding price, I would beg to differ in terms of higher priced rifles not selling. Per my description above, show me a completely original infantry rifle with matching serial numbers on the barrel, receiver, stock and top handguard that is still chambered for the 8x50mmR cartridge and I guarantee that I can find a buyer for inside of a long weekend. If the same rifle is from the pre-war Bulgarian contracts with matching numbered bolt and gas escape hole and I could sell nit for $750 or more.
Thank you for catching my mistake in misidentifying the photo of the renumbered receiver.
