Yes, some spindles have the "Z" (70-120 or 68-120... first number is bottom bracket shell width and second number is dropout spacing).
Campagnolo's own literature (their company newsletter back in the mid 1980s) stated that the "Z" signified nothing. My opinion? It was stamped on the axle for a reason, but the reason why was lost. But the significance today? No significance.
