Help Identifying Skeleton Key

[Searcher62]

I have a large heavy skeleton key. 6 inches long. Shows honest wear and heavy patina. It has a hollow stem with a hole on top. Could this be a key gun or what? It has a gap in the hollow stem about 1 1/2 inches long.

Thanks for any help.

Possibly an old prison key.

Could really be anything
Its old and cool though

Looks like a treasure chest key...
