Many thanks for your information gentlemen, it has certainly put my mind at rest
Piers - you are partially correct, the rear mekugi loop is missing and the front only just lines up, the barrel band was the only thing holding the barrel on
However, there are no other holes or signs of filled ones to suggest another stock?? I managed to clear the front loop and get a thin mekugi in to hold it together better (the rear one lines up with the missing loop)
Jan - the bore is 13.5mm +/- 0.1mm, see pic
Signature
underneath barrel - date?
Bore is 13.5mm, pitted inside
Many thanks again for your information
