@Troubleshooter I would appreciate that. What do you need from me? It does have a buffalo engraved on both sides of the receiver. Favors a Cape more than a Water, but I've been told that most 475 No 2's went to India so there is that.
Sourdough, you could check the barrels to ascertain whether they are nickel steel or Krupps (the latter would read as "Krupps Flusstahl") but based on the photos in your other thread on this rifle, I'm pretty confident that it is a Model 12. The engraving may well have been added by the distributor (or perhaps by Jeffery if the order was sufficiently large).
The "Season 1910-11" catalogue listed the .475 No 2 as available in the following rifles:
The No. 1 Pattern and No. 2 Pattern were offered in .400 Bore, with .450, .475, and .577 as options. But these were sidelocks, whereas yours is obviously a boxlock.
The No. 11 Model Rifle was a boxlock chambered in either .475 No. 2 or .450 No. 2, and offered with either nickel or Krupps steel barrels. However, the "forepart fastener" was a lever, whereas yours is of the A&D button type. So that's eliminated too.
The No. 12 Model Rifle was a boxlock in .475 No.2 or .450 No. 2 calibers. Barrels were nickel steel, 24" in length. No mention is made of the "forepart fastener" nor is it illustrated, so that remains consistent with the photos of your rifle. The rifle as listed in the catalogue was not engraved, which is why I think the water buffalo may have been added by the distributor. It was offered w/o ejectors (consistent with your description) and with (No. 12) or without (No. 12a) chequered grip. Ejectors could be added to the No. 12 at additional cost.
Based on all that, I'm fairly confident that yours is a No. 12 Model Rifle, retailed at a cost of £ 30 0 0. You'll need to run it through an inflation calculator in Pounds Sterling and then convert to US Dollars to determine whether you overpaid!
Hope that helps.
