Does anyone have a service manual for the MR12 first stage? I finally found a manual for the Proton 2nd stage, but still looking for the MR12. Just to be fair, I have quite a few manuals for various regs, and would be quite willing "give em up" for the MR12. Hey . . . this is starting to sound like trading baseball cards when I was a kid.
