What model is this JMP?

[goddamn electric]

I know they've been posted before but...

The 75 Marshall in these clips - Is it a lead, bass or lead&bass model? i dont know how to tell myself, or whether its even possible from the video, but im sure some of you amp gurus may know!

You can't tell from the video, as all the versions have the same face plate. Treetopper certainly has some good chops, and has put up some nice vid clips of his Marshalls.
  The circuits can be tweaked so much anyway, so it could anywhere from a lead (1987) circuit to a bass (1986) circuit, or anywhere inbetween.

Just my opinion, but it sounds more like a bass circuit to me. He looks like he has plugged into the bright channel (un-jumpered) (unless the amp is internally jumpered). So, in that case, there seems to me to be more bass frequencies than a lead circuit can provide on the bright channel.
  I await being proved wrong here !!

Sounds like a lead plexi to me.  It's just muffled because of the hotplate and the recording.

You don't really get those pinched harmonics from a pure bass amp.

I doubt it's a Lead & Bass 50w head as they have a circuit very similar to the bass heads, therefore are voiced somewhere between the lead and bass models (hence lead & bass, lol).

The bass heads don't have that much roar to them (unmodded), so I'd say it's got to be a 50w non-master volume head (1987).
