About 30 years ago when my parents moved up north one of my dads friends took on the job of curator of a new Maritime museum at Barrow in furness.
We got a guided tour of the place one day. They had a warehouse full of stuff, much of it irrelavant to the museums remit.
Guns, swords, artefacts by the ton. None of it ever to see the light of day again & like many other such places with stringent rules that prevent disposal.
Im pretty sure the maritime museum folded & was replaced by something much smaller.
Personally the last place i would put anything is a museum!
