404jeffery,

I'd think this can't be the same gun, as I know for sure that 100 were made in only 375H&H and 416 Rigby.

Could it be that it originally was a 100 year version that they might have switched barrels to 9,3x64?

Either way, I got off with paying a 4th of the price you mention! Are you sure the price wasn't in Namibian Dollars/Rand?
