I need a front derailleur for a '69/'70 Varsity

[bgorrell]

The one I have has "Schwinn Approved" on the outer band and on the seat post clamp. It also has "Patented Made in France" on the back of the rear band. Does anyone have any sources?

I know I have at least one. It has some chain rub but moves freely and should work well no problem. 12$ shipped.
