Many thanks for the suggestions everyone.
Unfortunately I am abroad at the moment or would certainly have attempted the move myself or with the assistance of my brother who is even older and punier than me.
I contacted 17 movers in the end. Responses ranged from no interest in the job, high prices (£1,200 plus VAT) or "over confidence" in the ability of a two man team to hoik the complete, unassembled machine into a transit for £500. In fairness they may have been possessed of extraordinary strength but I was reluctant to commit the machine to their raw ambition. I hope I didn't do them a disservice.
Fortunately Landylift had a cancellation. Hopefully the machine will be delivered today and my 5' tall, 7stone wife will be there. She may be small but I reckon the acquisition of yet another lathe will prove sufficient to generate feats of superhuman strength and she will position it exactly where I want it. Or just take a sledgehammer to it . . .
Now I need to shift the BCA jig borer and a Pultra to offset the delivery cost.
