I recently aquired a new track frame. It is neon yellow on one side and hot pink on the other. A PARAMOUNT sticker is located on the top tube and a bold SCHWINN sticker is located on the downtube. The frame has a small "P" sticker for a headbadge and another on the seattube. (All the stickers are under clear coat and the paint job looks very professional.) Looks straight foward. However, the frame has an English Threaded Cinelli S.C. bottom bracket with the serial number reading N6014. Did Schwinn Paramount builders / manufacturers ever use Cinelli bottom brackets? What is another way of determining if it is a real Schwinn? What should the lugs, brake bridge, and fork crown look like? The frame has a late 80s early 90s vibe. Please help. THANKS.
