Just acquired this British retailed Mannlicher and I don't understand all about it. It is very British with the round knob bolt rather than the butter knife handle. It has the original sling eye hooks on the old sling, flat top English checkering, both express sights and a bolt peep, 26 inch barrel, horn fore end tip, trap grip cap. Bore has frosting but should still be a shooter. Same about the pad on the butt. What I do not understand is the marking on it. It is British proofed, the serial number is 475 which I thought at first was a ledger number; however it appears on the root of the bolt handle, side of receiver and on the barrel. I took it out of the wood and it is not marked with a retailer - what a shame it was not marked with Rigby or Holland & Holland. The front ring is Marked Modell 1903 without the knurling usually found on Steyrs; however the side of the receiver is marked "Steyr 1906" - would someone with expertise in the rifles tell me what it is?
