Search ebay for "shimano ty05," which results in items like this:

What SurferRosa said. I use Shimano wheels just like those on my own Nuovo Record. No complaints.

Soma also sells a set, but they are like $35. Don't know if they can still be had, but the colored Bullseye Jockey wheels look really nice.

There are lots of 10t pulleys out there that might fit. The very best will be Suntour ball-bearing replacement pulleys, which conveniently came with reducer bushings for your derailer's 5mm diameter bolts.
Suntour, Simplex and Huret pulleys may turn up, but will usually have a 6mm mounting hole, making them more precious in the marketplace for those brands of derailer.

If the replacement pulleys are much narrower than .406" at the mounting hole, then you'll want to use a washer under each bolt's head, to keep the un-threaded portion of each bolt's shank from entering and damaging the threaded holes in the inner cage plate, and to prevent the bolts from possibly snagging the spokes.

I used aftermarket 10t alloy pulleys on this rear derailer. The pullies were narrower to better match my bike's modern 9s chain. Look closely and you might be able to see that there are washers under each bolt's head, to make up for the bolt's now excess length:

Post in the trading thread.
Something good to trade may find a willing soul with too many Campy bits.

I have been replacing the pulleys with the Chaser tech pulleys about $15 per pair but they are sealed bearing set that can be set to a 5mm bolt just ask them and they will send a correct fixture. Smiles, MH
