I recall seeing a WTB posting from somebody on the list who was looking for a BIG (32t or 34t) freewheel, maybe a week to 2 ago, and though I've searched the archives I can't retrieve the post.
So, I have a 7spd DuraAce silver finish FW with 13-32 teeth, in very good shape: not pristine but passable.
If this suits the OP, contact me off-list...I'd not be adverse to a trade for some Frenchy items I'm in need of.
Thanks for bandwidth,
