Selling a Vintage Fireman's Cairns Polycarbonate Helmet. The paper I found inside it says it is a # 880 Century & # 770 Philadelphian which is made of pure "LEXAN" Polycarbonate. Condition is "Used" by the obvious tell of the various markings on it. The exteriorhas the No. 72 on it in 3 spots (front & both sides) and the back has PHIL. The back brim on the inside has MOWBRAY & 53 on it. (See photos for these descriptions). It appears to be in overall great condition except on the inside brim where there is a foam padding that seems to be deteriorating from age and or past use. Please feel free to message me with any questions or requests for more photos. Selling as is as shown in photos and description. Thanks
