RT vs. RT Pro

[monkeyking]

(I thought I'd already asked this question, so sorry if this is a repeat, but I can't find the thread anywhere)

As I understand it, the first RT was largely incompatible with other Automag parts. Is this true of the valve? Are there RT valves out there that won't work on my 68? How can I tell them apart?

Yes, the original RT valve will not work in anything but the classic RT.

Anything that says ReTro Valve, RT Pro, Emag Valve, Emax, Xmag valve on it will work in any standard body (minimag, classic, rt pro, emag, xmag) so long as the correct on/off pin length is used.
