That brings back memories. I had one of those when I was a little kid. I turned mine into a chopper! It was the thing to do at that time. I cut some fork legs off another bike and just pounded them on over the other fork legs. Crude, but it worked! Barry
Contacted the seller regarding the S/N. It starts with a U, which is correct for the Esso Tiger. Also, the seat has the correct black piping as opposed to the silver piping on the Sears Screamer. I'd agree this has the specs to be a legit Tiger.
