How far should I restore?

[Fourfirs]

Progress! I've got the rust of the metalwork, glued the broken stock & ram-rod, and re assembled the weapon. Still a few things to do, some of the brass barrel-bands need attention, and I have to fabricate (or acquire) a trigger mechanism & serpentine. The gun will never fire, it still has a blockage in the breech area (possibly a charge?) and it is frail, as you'd expect of a weapon this old.

I don't know much about it, other than what I've read on this site, which suggests (which has been really informative). My late father brought it back from Oman in the late 1960s, he was with the Sultan's army fighting the insurgency. Sadly, its been neglected for a while, but not any more!
