Doug,

Your hypothesis is interesting, but I don't remember hearing that Lancaster made guns for Army & Navy with a Webley Scott patent. It may have been the other way around, that is Webley Scott building the same gun for both A& N and Lancaster, in any event this is mostly academic, if they look alike they were made in the same place in all probability. Yes, I had been in the Glagow Univ site, from where I got the production year and first owner's name. One next step would be to make a paid enquire where I would get the full order/production sheet, which I don't think will provide much additional info. I must confess I have been a little slow on this path. On the other hand, I can see that you have done a thorough work with your gun and I am sure I have a lot to learn from your experience.

Regards,
