State of over "1 MILLION 150 THOUSAND" Concealed Carry Licenses.
Welcome from Colorado and thank you for your service, but OUCH. We collectors do not alter antique firearms to suit our taste. And especially historical firearms. We should talk. Any who welcome to the forum. I have been on numerous forums over the years and this is the only one I am an active member of. There are some great guys on this forum and many have vast knowledge and are willing to share.
I too have my Grandfathers Trapdoor.
It is in excellent condition, looks almost new.
Purists would scream but gramps left it in a small space behind the bathroom plumbing, there was a water leak for some time, the finish was gone when Dad picked it up.
He redid it. But is is nice and shootable. Not all guns can be saved with the original patina. Good for you on saving your family heirloom as close to original as possible.
We had one uncle who came to deer hunt with us, he used the trapdoor but never saw nor got a deer. Dad and I would shoot 410 shot shells out of it once in a while.
