This is something we found with a metal detector on our property about 20 years ago.. There is nothing that you can read on the gun and it is about 31 or 36 cal.. There is a lot of rust.
It is 5 shot and at least one ball is missing. I do not see any caps on it.
The wood is about half gone and every time you handle it it does loose little bits of the guns surface rust
Just some fun eye candy
