This is a very unusual, boxed diving mask from the 1960s or 70s?

Amazingly, it comes with it's original box (impressive, but slightly gruesome illustrations)

Tempered glass lens, chromed metal ring and rubber body.

Amazing condition as seen (not sure how reliable this would be to use now, but a great piece of history for display

 

Note: This item is 100% original used vintage ware.
