John, thanks for taking the time to answer. I may have someone interested in trading for mine and I have seen guys here on Trad Gang refer to them as ACS Z CX once in a great while so I thought I'd ask.
Also, I got a response from Dan Palma through your website who said pretty much the same thing except he said:
"Terry it’s just a Larry thing, it doesn’t mean anything.
-Dan"
I'm not sure who Larry is - unless that is what the "L" in O.L. Adcock stands for?
Just adding to the legend of the "Z" I guess.
Thanks to everyone who chimed in.
Terry
