Very well fabricated full vision Flip-up protective mask with adjustable head gear. It has a 1939 Patent date and was manufactured by Industrial Products Company, Philadelphia Pa. Plenty of room for corrective eyewear underneath and works extremely well! The plastic lens is in good condition too. Looks like it could easily be replaced if you want a perfectly clear one. Nice piece for the garage or work shop! Free insured shipping to the lower 48. Thanks for looking!
