I've got a pair of near mint hoops.
600 tricolour on Mavic Open 4 CD, the front was hardly used which shows in the braking surfaces and the rear whilst it's had a little more is still in really nice order.
Hubs are super smooth, a little tarnishing to one of the qr levers but otherwise good. They've been fully cleaned
36 SS spokes per wheel.
I'll be wanting top dollar for them though as I need some new wheels and these are going on the bike otherwise.
Asking £140 plus courier
