These were state of the art in 70's and early 80s  Mfgd by National Hydron in Pennsylvania.  See two Cycle World ads (one from 1974, one from 1975) in the pictures (actual ads are not inlcuded withh goggles, but feel free to print it on your own).

Box is dusty, and goggles inside show their age just from sitting in box on shelf for 30 years.

-Lens has multiple stress cracks - probably due to heat/UV over the years.  I see you can buy new/good replacement lenses online today for about $10.

-Not sure about condition of foam rim/cushion - it looks ok, but older foams sometimes crumbles

Frame and strap look in real good shape.

Again, these are new in box, but vintage 80s.  If you are going to use them you will need new lens for sure.

Ask any questions, and thanks for looking!
