Any picture of the bottom of that lid ? Mine seems to slowly cone downward 1/2 an inch also would they have a corks in them if it is what it is doesn't seem like it would seal well ?
The map tube idea got me thinking I am wondering if anyone thinks this could be a field telescope lense cover have seen some plane brass. Responses would be greatly appreciated !
