If that pistol made it to the jungle, without extensive journals and a strong accounting of provenance, it may well be impossible to know for sure all of it's history -- especially in regards to it's scheduling of tunes and services.

Back in the good old days, and in the worst of conditions, a broken spring or fubar'd tumbler got repaired by whoever could do it and get it back into action.

I look forward to hearing what you come up with, also very much look forward to better photos of the pistol.

Detail on whatever's remaining of the engraving on the rib, the locks, and the action -- also a complete look at the proof marks on the barrels and action will be a great source of information on this neat old gun.
