George,
I have a project gun almost exactly the same as yours. My Boss was built in 1860 and was a pinfire conversion. It is my estimation that your gun is not a pinfire conversion but rather a very early centerfire. The pinfire gun I have is more squarish than yours in the balls. Mine still has a good set of barrels but it will require a lot of work to get it back in shape. I am not doing the project for an investment, rather just to have a nice Boss I can shoot a few birds with. If I want to invest money in something that will make me money, I put that in my business. Like RocDoc says, it is a nice way to have a hobby which takes your mind off of things once in a while. Even if that only means you never get past the dreaming stage of what if. Good luck on your endeavor!
