If they are from the late 80s, this might help, I have built up a couple sets of these rims, clincher version, for my rides. Put a set on my lowly Trek 400t, really transformed that bike for the better. Standard version, would have preferred the XLs, but they are hard to find NOS. Got my sets from Italy, paid about $200 per set, including shipping, and they were brand new, in original packaging.

I think this is from the 87 catalog
