Old Football Helmet

[netennis]

I appreciate the information individuals have provided. I am providing additional pictures (front, back, and inside) of the helmet. The helmet came from a good friend of mine (85 years old from Pennsylvania) who has had it for years. It originally came from a hardware store in Philadelphia owned by a man over 80 years old and started by the over 80 year old man's father. Comments were made about the straight cutting of the leather. You will notice the pictures of helmets provided by individuals had very straight cut leather panels also. The helmet I am inquiring about additional information also is made of leather not synthetic material. It is rough on the back side as many pieces of old leather I have seen. The chin strap is shown in some of the pictures (as well as an old shoestring that was attached to it for some odd reason and has not been removed). I did check with the companies that make repo helmets and they felt it was original. Thanks again for all the help.
