I'll second that. How old is the W & S? Some of the later ones; 700 models for instance, did employ a lot of machine made parts although hand fitting would be required. Holland & Holland bought them out. It may be a slim chance that they may just have some old components that could be fitted. I would give it a go via e-mail as you have nothing to lose. Be prepared to find a good Gunsmith though. Good luck! Lagopus.....
