Help IDing some British and European firearms

[Matchlock]

I think nobody struggling for serious study can ask stupid questions; it's the answers that can be stupid.

This is a real riddle piece indeed. Though, as you noted, it looks much like a regular military musket at first sight, some details do not seem to match, e.g. the stylized flower engraving on the rear end of the barrel. Unfortunately, neither could I find a certain Corson (or Carson) Carr in any of my records, nor have I been able to identify the marks.

All we can do is hope to find someone here who has specialized in British and colonial American flintlock muskets.

Best,
Michael

A characteristic British flintlock mechanism, signed by Grice and dated 1762/9?.

You were absolutely right in pointing out the difference between the crown on your gun and on this lock bearing the typical initials GR, for George (or Georgius) Rex.
