Subject: [CR]Campy hub bearings...sizes?

I think I recall a prior posting that stated that NR/SR front hubs used 3/16" bearings but I recently tore down a front hub that had 7/32" bearings ('74 lock nut date code) and spun very smoothly. Now for the real issue, I have a pair of 3 piece Campy track hubs that apparently were built up from shells ('87 lock nut date code) but the front is not particularly smooth and is difficult to adjust to eliminate play. It is assembled with 3/16' bearings, 10 per side. What is the correct bearing size for this hub and how would I identify the correct cones if what I have is incorrect?
