Dad has put the original master cylinder back on. He found a few days ago (can't remember if I posted this or not) that the piston seemed to be getting stuck inside the bore, so he put it on his lathe and cleaned it up before replacing it, and now the piston fits well and flows freely. We still have no pedal though.
Dad gets under the bus to bleed the brakes, and I'm in charge of the pedal. On pumping the pedal slowly, there's no resistance whatsoever, but when I pumped very fast there was resistance for a very short time, like the piston caught on something, then gave way and the pedal would go to the floor again. All during this there's no pressure coming out of the three pipes on the M/C, no pressure at all to the rear brakes and only a slight dripping of fluid from the M/C to the front brakes (this is when Dad takes the pipes off of the master cylinder and watches as I pump the pedal.)
I've just found out that Dad pressure bled on the other Cylinder, the Mk 2 cylinder, so his next step tomorrow will be to use his pressure bleed kit on it.
I've taken some pics of the M/C and also a couple of video clips, including what I said about the strange behaviour of the pedal. Hopefully this link should work and you'll be able to see it all.

Thank you all again, so very much for wracking your brains as much as you are.
