This was made by the Mine Safety Appliances Company, Pittsburgh, Penn.
The sticker on the inside of the hat says that this hat complies with
the service specs of Jan 7, 1959.
This hat is in Great (almost mint) condition. NO scratches or dents. It does have some very minor dings on the top.
It still has some glue from where the original stickers were placed on the front and the rear.
