This person holds the name to Williams & Powell and can still make guns to that name.
http://www.wrichardsguns.co.uk/index.shtml I don't know how complete his records are but may be worth contacting for details. As above, Stanton locks were all hand made. I had a similar problem with a right hand Stanton lock recently which needed a replacement main spring and sear spring. My Gunsmith here in England is one of the old school and has a large store of old parts 'just in case' and I was lucky enough that he had some that would fit and work o.k. If you can find a similar old timer then maybe you could be in luck. Lagopus.....
