Years back I had one of these. Serial number 709.
Was a 8x57 that had the full on "American-ization" sportizing done to it.
Weaver bases, low bolt and safe,set trigger removed and a Jeager installed, recoil pad.
I straightened it up some, leather covered pad, rebarreled to 275 Rigby H.V.
Fun gun that I foolishly sold.
