Yes, I do. It's a Schwing system, as described here. A good feature is that it can be fitted without drilling into your boat, as it mounts onto the pushpit. However, it was originally fitted to a Vancouver 28, so your boat might be too much for it, especially if the sail plan isn't well balanced. It's currently in storage in Edinburgh, but I can readily deliver to marinas in SW Scotland.
I've been looking around for a used windvane too, and one for a reasonable price seems to be hen's teeth. Looks like the known brands fetch silly money 2nd hand even. Starting to consider hassling people in yards and marinas if theirs look under-used!
Interesting one that, but am sure it'd be not up to my boat (also 35, but steel and wheel helm).

I would suggest you look at this site www.cruisenews.net/cgi-bin/windvane/windvane.pl Look up Walt Murray's designs either from that site or Google. His 20/20 design is probably what you need, costs $20 and takes 20 hours to build. I have always had trouble getting my head around how a pendulum servo system actually works, his diagrams and photos make it all so simple.
I was looking mostly at Monitors- seemed to have very good feedback, then went towards Hydravane- nice and compact, not all the external gumf, but looking through a bunch of old mags tonight, I've seen some examples of Aries (always looked rather clunky) which are linked up to small Autohelm Tillerpilots in a nice way, and now my urges are going this way... May be hunting one of these soon myself after all.
Jem.
But can I find a 2nd hand one this summer?... That's another matter. Be a good thing if so, emergency steering and improved autopilot potential too.
Cheers, Jem.
you can link a tiller pilot type autopilot to a Hydrovane - there is a handle built into it for using the rudder if the main rudder fails... I am pretty certain you can add a Tillerpilot to most of them - onto the vane weight but Hydrovane is designed to accept one.
