some random parts on a shelf

Maybe not the best blog posting but you know the old saying, the parts in the picture are worth a thousand dollars, or something to that affect.


So we have from left to right-
*1950s Campagnolo Gran Sport front derailleur. nos
*Mafac Tiger brake
*1930s-40s Schwinn script brake levers
*Hill Cycle frame sticker


Can someone name that brake lever that you can just see a piece of on the left? it's a rare one.
