well done! that is absolutely perfect! and I'm so glad you're keeping it.
The thing I have always loved about 'colonial' weapons is that they have a unique, rustic charm that makes one wonder of the adventurous tales they may hold. While it cannot be said for certain this is such a weapon.....by the same token, it cannot be discounted either.
Many of these weapons, or their components, had extremely long working lives and often ended up in situ in various settings for generations until finally being sold off, and ultimately sometimes finding a good home , like this!
This is my 'colonial', and has had some work as well. These were prevalent through New Spain in Caribbean, Gulf areas through 18th c. into early years of 19th.
