Francis Lovell now owns AG&L. He has a web site.
Good luck getting the information you need. You may be better off posting your question here.
A few years ago I owned a nice 1912 Grant with new barrels that I was told by the maker. When I asked for info on my gun all I was told by them is they didn't have a record of it.
Francis Lovell has his own gun shop so not sure how much he is into AG&L.
But he is a nice guy.
