What bike is this?

Please tell me about this bike. What is it worth? I am going to keep it, just want to know.
I got this bike from an old timer and he got it in the 50s at Sears but wasn't sure. Does anyone know what it is? I think it may be an old Spaceliner (J.C. Higgins?). Springer front end, hook for a tank but I don't have it. I need to clean up the rust on the chrome, and treat the leather on the seat. She's a beauty, and I even got a bell for the handlebars from the 50s yesterday at an estate sale around the corner. What are the odds. Paid $2.00 for the bike and $5.00 for the bell. The bike is missing a spoke and needs some love, and she'll get it.

Thanks and love the show.
