Bit old school for the cool kids these days; unless they have a laptop and cam, they really do not want to know.
Seen a few Cogsdill videos recently for their zx boring/turning systems, that is machining porn.
Vertical borer, try the small independent dealers north of Manchester; I saw someone selling a 72" webster a couple of months back, can not remember who.
Same problem, too old school, needs someone who knows what they are doing(ish) rather than a laptop.
Edit, Electromotion have a 72"WB with elevating rail, in Melton mowbray.
