The bike was made in England and is very likely a Raleigh Twenty wearing an extra decal and a Supercycle headbadge. Other than that, and I know little about these little folding bikes, it appears to be a Twenty. The cranks are cottered. I did not take any other pictures since I am not all that interested in the bicycle. It and all but one of the others will be donated to Bicycles for Humanity tomorrow morning.
The picture depicts only part of the pile of vintage roadsters - everything from Raleigh to JC Higgens. And there are just as many Ten Speeds. All have been selected for rebuild and sale based on condition of the bicycles. The junky ones were stripped and used for parts, the scrap being sold off to the local scrap yard.
