I recently went to Albright's for a gun fitting. They have a young guy there named Alex who was very knowledgable and pretty passionate about his trade. Not sure what his specialty is, but there were a good number of vintage doubles there for various work. They also had a couple of used AyA guns for sale, so I am sure they do some type of repair work on them.

The number there is 410-820-8811. Good luck, and let us know how you make out.

Kind regards,
