I believe that Mannlicher called it the 9.5x56 and it was Mauser that used the 9.5x57 designation. Or that was what I was told when I had a Mauser 98 actioned sporting rifle in this cartridge. The drawing that Peter Labbatt sent me whne I was trying to find out about my rifles is dated 19th March 1908 and is of the Westley Richards .375 Bore cartridge. This drawing is from Eley bros and it says traced from WR drawing received 17th Feb 1908. Will have ti see if I can work out how t scan to file then post it here.

If not I will just have to photograph it.

Nice find BTW I am not green at all .................................. nope not a bit.
