Big Shrek

Well, you kept it in the garage for a reason...must have some memory value...or maybe it was a family thing? Anyway...there's always melting some soft metal like pennies into the chamber and then putting it into a glass rifle case, then hanging it on the wall
And honestly, it may not be as dead as you think. Many of us have brought some pretty rusty beaters back from the dead to be useable again. Some make pretty good door handles
