What is it?
 

I picked up this bike that was converted to a trike because it looked like a fun project. But, I can't seem to identify what the bike part is. Any ideas? There's no serial number, or badge on the front. On the seat tube, it looked like it may have said custom deluxe, and it looks like there may have been a shield with a plus sign. I'm not sure because it was painted over. The only marking is on the chain guard and the person I got it from thought that was an old phone number. Any ideas would be appreciated.

I suspect the conversion and bike were painted at one time. The bike's front fender and chain guard have that late 1960s/early 1970s look. The curved down tubes suggest USA as does the 1 piece crank. The brake levers are not the lower cost steel stamped designs common to low cost USA bikes. The pedals are.


As to serial number check the seat tube at it's upper and lower portions, the left rear drop out face, the sides of the head tube and under the B shell. Andy.
