GULL Snorkel

This is a GULL snorkel set.
I was a resort diver about 10 years ago and dived 20-30 times before it was stored away in a closet.
After each use, I rinsed it with fresh water and dried it before storing it in its case.
There is noticeable discoloration due to age, but I don't feel any particular hardening.
(I'm an amateur, so I can't be sure.)
I took good care of it, so there are no noticeable scratches on the lens.
