Well , I have been doing quite a bit of research on my Lancaster pair retailed by J. Graham.
I am attempting to verify a couple of things.

1. I have read that Lancaster only made a dozen over under side lock shotguns.........does anyone know where I can verify that information...?

2. and if in fact Lancaster only made 12 of these guns, would it be possible to have the records checked for whom these guns were made for and sold to to verify the J.Graham purchase....? a long shot I'm sure but maybe possible.

any help would be much appreciated.
