Pretty humbling to know that Unk trusts me to take care of it.
I'm thinking about having a competent gunsmith take a look at it to see if it's safe to fire and if so load up some black powder shotgun shells and take it hunting like GG Grandpa did.
You should be able to get some low pressure smokeless shells from RST or Ballistic Products that would be safe to shoot if it is in good shape. I have used some in an old Damascus double with good results.
