This petite Schwinn Paramount is one of the newest additions here. The Stronglight Mod. 93 crank arms have been shortened and tapped, effectively now making them 145mm long. The frame is Reynolds double butted tubing and Nervex Pro lugs, but the fork crown is the older 1950s design. The fork also has an unusual rake for a track fork, probably to provide ample toe clearance. It uses 24" tubular wheels.
Oh yeah, no Paramount headbadge, but instead a Hill Cycle sticker, so probably sold through the legendary Philadelphia cycle shop.
