Here are two more masks I've added to my collection.
One is a Nemrod "Toledo" in fair condition (rubber slightly perished at creases of nose pocket but good enough for shallow diving or snorkelling).
The other is an elipse shaped mask with no finger pockets for the nose but with the clip style band attachment around the glass as opposed to the older bolt/nut tightening system.
No name at all but on one side of the interior the mask says "MADE IN U.S.A." with a "2" below. On the other side it says "Pat. No. 3027561". Again, rubber in fair condition and another good snorkelling mask.
Any ideas as to the maker or where I might look for who holds the patent?
