That looks like a '64-'69 Huffy-built bike. the serial number on the rear dropout should give you the exact year, I can decode it for you if you post it.
With all of the special trim, emblems, and the original paint gone, I can't tell you if it was a Huffy or Monark brand bike...it might even be a Belknap. It is even more difficult to determine the model. given the color, it might be a Camaro. Huffy didn't have too many dept. store contracts at this time, most of the Sears, Penny's, and Wards bikes were built by AMF or Murray. I wouldn't try to restore this to factory specs, it will cost you a lot more money and time to do and you will have to butcher a lot of nice bikes to find some of the parts. I think this would be a great candidate for a custom bike.
