Do yall know anywhere near philadelphia where I should take it to get looked at?
There are several antique arms associations in PA that regularly hold gun shows. If you google it, you can find something near you. There would be people there that can help you.
The stock doesn't really bother me that much, it's possibly just the angle of the photo. We just ran into that issue in another thread, something can look odd at the wrong angle.
Here are some comparison photos to help you see what I mentioned upthread. The first one is comparing the cock on your musket to what it should look like. The piece I am comparing it to is actually a French musket, but this is what it should look like, I am just using my own photo to avoid any copyright issues. The cock on your musket is too small overall. The heart shaped cutout area is far too small, the screw that holds the top jaw should be entirely on the left side, but it is centered instead. If you google flint muskets of the 1816 pattern you will see that the design of the cock never varied and the one on yours is clearly incorrect.
If that was the only issue, one could argue that the cock was replaced. However, the top view of your barrel clearly shows the outline of where the percussion cone was once placed. You can even see the slightly different discolorations of where new metal was welded to replace the threaded hole versus the area that was previously "upset" to form the flat spot for the cone. You can also see where the metal split a little bit on the bottom side of the curve due to the stresses induced when it was recontoured. The area of darker brown on the barrel is probably where work was done to mask the pitting typical of percussion conversions and then some sort of antiquing solution applied.
Here is an example of a museum piece that you can compare it to, I think there are some other parts used in the reconversion that look a little off to me as well.

It is a very well done reconversion overall, really well done, although I personally wish people would just leave them as percussion. I have no idea what it does to the value. I like the history of any old gun, regardless, enjoy it for what it is.
