Being that Les O'rouke provide a picture of John Dawkins' .450 NE Rigby (cased) for Graham Wright's "Shooting the British Double Rifle" perhaps he has a source of information/contact for John Dawkins.

Is Les a member here ???

NitroX, If I read correctly you have the forend off Bill Jenvey's .465 Holland. Would you be prepared to share the story of how you came about it ??? Perhaps you know where the rest of Bill's Holland is ???
