I would second the recommendation of Douglas Tate's "Birmingham Gunmakers", and add Desmond Mills' and Mike Barnes' "Amateur Gunsmithing". The first covers a lot of the history of the A&D boxlock and and the second, inner workings and stripping and reassembly. The bad news is that both books are out of print and are pricey on the secondary market. As best I remember I paid $120 for "Birmingham Gunmakers" and $90+ for "Amateur Gunsmithing" But for the inner workings part you could watch Jack Rowe's five part series "Strip and Clean a Boxlock" on YouTube for free.
Best, D.P. Scurlock
