Which Laney head had some kinda attenuator or master-master volume knob on the back?

Kick-ass amp, though. Rhythm channel matches your "out-Marshall a Marshall" description; lead channel is more modern.
The Ironheart is the one that had the "watts" knob, but that knob was on the front, not the back.

Nah this was an 80s or maybe 90s looking thing.... and the knob was on the back where the speaker outs are

I used a few of the Laney AORs back in the day, great amps, but I don't remember any with a knob on the back. Are you sure it wasn't modded to add a PPIMV? I actually may have done that to one of mine.

PPI...MV?
I think it looked stock though...

Post Phase Inverter Master Volume
Was it a 50W single channel MV? Or a channel switcher? I'm almost wondering if came across one of my old amps. It was pretty awesome!
Did it look like this on the front (not my amp, but same model)?

Actually I thought it might have been... but then I saw a chromefaced g-something 50w model and now I'm just not sure
Regarding that master volume, is that the equivalent of placing a volume box through the effects loop, or something else entirely?

Not exactly, most master volumes are in the preamp, usually right after the tone stack and before the loop, although there are exceptions, but generally all are before the phase inverter. The PI is the last "preamp" tube, although technically it is part of the power section. The post PI master volume puts a dual pot directly between the PI tube and the power tubes, which allows the PI tube to be driven harder and also, according to most, better control of the volume with less effect on the overall tone. Of course, when you turn it down, you still aren't pushing the power tubes hard, but you are getting some more saturation from the PI tube.
PPIMVs are generally a modification, especially to non-MV amps like old 4-input Marshalls although even on MV amps like JCM800s and the Laney above, again, they allow the whole amp to be pushed harder right up to the power tubes, you can just crank the original master and use the PPIMV to adjust the overall volume.
Sorry, can't help you on the Laney without more info. Laney makes some great amps, and I was a fan of the old AORs back in the day, but they did like to be run loud, even the channel switchers with all the pull boost knobs.

This one has a level control for the DI out on the back, but not a master - https://www.guitarcenter.com/Laney/GH100R-100W-Tube-Guitar-Amp-Head.gc
