Set of Brass Furniture

This is a set of very highly polished Brass, it appears to be possibly sand cast originally.
Would be suitable for a large fowler, musket etc.
It has a very deep tone of colour, moreso than our 'Yellow Brass', it was not produced by us and so origins are unknown.
The Trigger Guard is 263mm long.
The Butt Plate is 117mm high and 38mm wide, with a cut out for a patch box -(not supplied). The tang section is 110mm long.
The ramrod pipes are open and have been formed.
