Good morning Niall,
Very nice to see you here. :-) It appears Welcome is in order!.
Yes, I have and will take more photos.
The lock has no bridle on the tumbler,but all seems in fairly decent order, apart from the bloke with the soldering iron crushing the half and full bent positions in the vise! I believe I can peen them back though.
I believe you are spot on re. the date.
The bore is about 20, but not measured it yet. Yes, a good swamp on the barrel, and both loops in good order.
Buttcap is two piece, a screw holding the base.
Again Niall, Very nice to "see" you!
Bob,
The borasic is something I will bear in mind. For bores I have used white vinegar, but it Will remove any remaining finish, so Not for the outside.
I do like the Caustic soda, as it destroys organic matter, like old oil, that causes the rust to adhere to the iron. After a caustic bath, the rust more or less falls off, without any surface damage to remaining finish.
A few detailed images;
You will notice the lack of trigger plate, and that maker's mark is obscured at present. Also, the mainspring was bearing on the lower mortise, so the wood has to be pressed back up to the lock.
The break was full of glue, the wood not touching at all. Fortunately, the glue is of a type that softened easily with a mild furniture stripper.
Got the broken stock apart now, and most of the old glue cleaned out.
Needs the trigger-guard tang making. was missing.
I don't know why I started messing with this now, I only took it to the workshop to have a look at it!
Got piles of other projects half done.
More as and when.
PS,
the "No trigger plate" could be applied to more or less any early gun or rifle, but appears a little uncommon.
ATB,
Richard.
