If I understand your email correctly, my experieance is been different then yours.
I am currently using two Campagnolo rear derailleurs (NR Pat 75 and SR 1st gen Pat 73) with these pulleys and the original washers - one washer on either side of each pulley. The washers are plenty thick enough and I have no problems running a Regina cheapo (all black but otherwise like the Oro) and a Regina Oro chain on the other. I know the washers from one set is original as I took the whole set-up up from its sealed bag. I still have another NOS sealed set and the washers appear the same too. Interestingly, the washers are not metric while the bearings are.
I do agree that the aluminum pulleys are noisy and wear faster then the plastic factory units.

Ahh, but the Bullseye washers were too thin when using 2, and too thick when using all 4 (2 per side). When using a 7/8 speed chain, you could use 2 (1 per side), but the NR/SR bolt heads would protrude a bit. I guess it wasn't only standard bearings, but also standard washers. The obvious solution is machining custom washers...
Also, the aluminum pulleys are noisy, plus they wear faster than plastic. Still, I raced with them for many years with good results. Not a single race I did not finish due to pulley failure ;-) -- Jan Heine, Seattle Editor/Publisher Vintage Bicycle Quarterly http://www.mindspring.com/~heine/bikesite/bikesite/
