I picked up this step-thru today. There is no indication of brand on the headtube or chainguard, nor a serial number I can find. I am thinking Sears/JC Higgins Spaceliner that is missing the tank, but that is just a guess. Can anyone identify what brand it is and perhaps approximate year of manufacture? The seller did not know. It has obviously been repainted, probably more than once. Someone went through a lot of effort for the current paint, the hubs and spokes are pink, with blue nipples to match the rims, fork pivots and fender tips.
