I have a friend who owns a tavern .On his shelf is a game worn Packers one bar Riddell TK suspension helmet. Inside the helmet written in marker is Mercein on the band of the suspension system. Helmet has some wear. Very cool. Now......I am just throwing this out there for consumption. I have no idea whether or not he would even consider selling it. I can run it by him if you want to give me some ballpark figure of what it might be worth.
