Whitey got his Field's sidelever Martini from me and I got it from the importer, Thad Scott. It began its life as a 577/500 No 2 Westley Richards with a full-length rib but had been converted to a 22LR target rifle with the rib dovetailed for a globe front sight and a folding tang sight was scabbed onto the hump of the action. It shares the same slim wrist as on the other 2 Field's rifles shown here, as well as the lever-lock for the sidelever. Basically identical to the one shown except for the sights and rib. VERY high quality throughout, except for the conversion sights (now 86ed of course).
Regards, Joe
