Early Leather Head Harness/Helmet...What sport is this for?

[CarltonHendricks]

I picked this up last night on eBay...when I first saw it I went ga-ga since I'd never seen one before...there were no bids and it had 9 darn days left…I think the opening bid was $10.00…I hit up the seller for a BIN and she said others were asking for one too and she didn't know what it was worth...Against better judgment I made an offer.. I say better since the next person she tells can always top it by $25.00 and you're out...a couple hours later I got an email from the seller that someone offered her $45.00 over my offer…So I offered $25.00 over their offer…I sort of thought it was over at that point and I wouldn’t get it...A few hours later I saw she closed it...next thing I know I got an email that said she was going to relist it at 7:30PM Central time...but it was confusing after that...it sounded like she was going to put it back up with a BIN for the amount I offered…but the wording wasn’t clear...I noticed she had 35 feedbacks so I know she's still in learning mode…So I had to wait about 3 hours to see what would be…

So finally 7:30 rolls around and she had a BIN of $250.00 over what I offered….with a Best Offer option…At that point I started back peddling mentally since I hated to spend the money anyway…I just let it sit there for a few hours to see if it disappeared…Then I got an email that all I had to do was make my offer and she had set it to accept that amount….Finally I pulled the trigger….Today when I got up I felt I made the right decision…I’ve seen tons of leather football helmets but this was the first one of these I’d ever seen.

So…I’m pretty sure I know what it is…but would anyone like to give their opinion?....I’m told there are no markings…when I get it maybe I’ll find something.
