Another vote for a Korea-specific sub-forum!
As a retirement project I am researching diving equipment companies around the world still engaged in the business of making traditional fins, masks and snorkels. A recent eBay acquisition was a Korean-made diving mask that came in an old-fashioned cardboard box displaying the manufacturer's products on one side:
I've conducted several exhaustive online searches resulting in many sightings of the Daihan diving masks pictured centre in the second and third rows above. These masks are currently on sale on a number of Korean online marketing sites.
The other products illustrated have proved highly elusive, however, in particular the fins top left and centre. I've noticed nevertheless from various websites that they are used by Haenyeo divers on Jeju Island, e.g.
Can anyone shed any light on the Korean company manufacturing this basic gear? Here is the firm's logo:
I am puzzled by the dearth of information online about the company and its products. If it's any help, the mask is embossed with the English words:
DAI HAN SKIN DIVING MASK
MADE IN KOREA
MARINE SPORTS GORAE OVER THE SEA.
The top of the mask box is overprinted with the words "DAIHAN DIVING MASK" in English and "대한 황대 수경" in Korean. Although my knowledge of the Korean language is virtually nil, I was able to figure out that "GORAE" was a transliteration of the Korean "고래", meaning "whale" and presumably a reference to the firm's logo.
