Most aero brake ever designed* - reported to save you 0.5 s km, and/or 5 W in power output, at race speeds when mounted on the front of your bike. In very good condition. Intended for use on front (or under b.b.), but can be mounted on rear seat stays of, e.g., a P3C with a little ingenuity (let me know if this is the intended application and I can provide some assistance). To make an offer and/or request pics, email me at acoggan at earthlink dot net.

*Well, not counting all the new integrated/proprietary designs.
