Classic curiosity?

[bluefan101]

I have an old 68 Automag valve, from before they started doing stars. The serial number is in the 18000 range and was wondering what, or if there is any difference between what I have, and a Classic valve, mechanically or phenumatically.

Nope, there's no difference between yours and the new "classic" valves other than different laser engraving on the outside of the valve.
