Please help ID marks on blunderbuss

[fernando]

This is a blunderbuss in a non glorious condition; that is is to see.
What seems more difficult to clarity are the marks on the barrel and on the lock. One could instantly say that those punctions on the bronze barrel are British proof marks, but i wonder; somehow they look rather funny (to me).
The mark on the lock could well be that of a known lock maker, but i can't figure out for myself.
Could any of you guys give a hand on this enigma ?

Dear namesake

The hallmarks are Birmingham proof before 1813. The gunsmith punch appears between the test can not distinguish if WW or VW

The other inscription is in the timber?

Dear namesake

The manufacturer of the barrel appears to be William Wilson, and the lock seems to read "WATSON" but would need a better picture, to see if there are more letters

A better picture of the name would indeed be welcome :o :D
I also noticed that the picture with the name in it might be upside down?

Congratulations . Nice find ; very Pirates of the Caribbean. Before someone else points it out the stock looks early pattern Brown Bess but without details of the inletting for the missing brass work cant say exactly when . The lock profile looks post 1755 Long Land but the give away is probably the lack of a frizzen bridle and the leaf shaped terminal to the frizzen spring. Both characteristics seen on Sea Service weapons. May not be an ordnance product but looks like it may have been assembled from parts destined for the ordnance system . Sea Service seems to have been the rough end of production hence anachronistic features such as bridleless pans and parts which stylistically don't always appear to belong in the same timeframe .

Thanks a lot for your comments Gentlemen,
This gun is not yet in hand; when it does, better pictures will be taken.
Fernando, your guess on William Wilson must be right. But i don't think that Watson is the name on the lockplate; future will tell.
Very good remarks on the whole piece, Raf; the whole text has been well noted.
