I own a Coral tempered glass diving mask. It's very special to me not just because the tempered glass makes for amazing visibility. It was my grandmothers diving mask when she went on her tropical adventures. It must be 20-30 years old if I had to guess. It's been a very trust worthy mask but the strap on it snapped and the rubber around the face seal is starting to crack. I wanted to contact Coral about it but I can't find them anywhere. Have they gone out of business? If so is there anyway to replace the strap and fix the wear on the rubber? It's a shame I would have to hang up such an old mask.
