Have a pair of Japan-made Frogskins headed my way, with metal hinges and fire iridium lenses. Seller seems to think these are from about 1990 - was there a reissue on the look of the Generation 1's then? Or is this a mistake by the seller My internet sleuthing skills aren't proving too well right now. Was hoping some of you hardboiled Frogmen might be able to give me a hand. Thankss!
