Updated with revised quantities. Upon closer inspection last night, I realized that two of the three pairs of Mavic GP4 red label rims are NOS. They had NOS tires on them that I ended up selling separately, and I didn't realize the rims themselves were NOS until I took the tires off and could see clearly that tubulars had never been glued to those rims. So I've re-classified and updated the price accordingly, although they are still 50% cheaper than the cheapest option on eBay ($80 for a single rim, whereas I'm offering them for $80 a pair).

I also cleaned and polished the mystery used silver tubulars and will take some photos. Planning to offer them as a low-priced lot of five for $100 shipped.
