First, welcome to the board!
Second; it appears to be a very well made gun from your pics. Always a nice touch to see those hollowed pin ends that were flared to keep them there. Engraving is also well executed, scrolls being the toughest to execute.
Third: I'd go along w/prior advise to shoot it 'as is' for a while first, but w/the proviso that you spend a little time on a grease plate to see how the loads you intend to shoot perform. I'm speaking to simply making a hard focus on the centre point of the plate and firing as you bring the gun into play. Its a good method to both see where it is shooting for you, but also lets you take a look at the pattern and is distribution. Do that for a box and you'll have a very good idea of whot you are dealing with. Just my two cents; opinions vary to its worth and that's perfectly fine w/me, but if you do that you will have a much better idea of not only how the gun is shooting for you, but also what you may reasonably expect from it performance wise w/a given load. If you reload, you have even more options at your disposal. Just saying.
