Thanks! It looks like the anti-reverse cam spring, but you'd be surprised how different pieces are from reel to reel. I was just trying to see if anyone knew who made the Scheel's branded ice reels so I could get the schematics from that company.
Usually, stores like Gander, Scheels, Cabela's, etc will have one of the companies like Diawa, Shakespeare, etc make reels for them with the store name on them. Once I can find out which company makes the Scheel's branded reel, I'll start looking at the schematics from that company and find out for sure.
