Thanks all, I definitely have something to work with.
I did try Aldershot first of all but they have now changed their ramps and cited that as a reason they couldn’t do it.
I remember them fondly from taking my Harley ( Heritage Springer Softail) there for an MOT many years ago. A LOT of chrome and leather and white, the model was on the centre spread of a big book about the history of HD’s. I drove it in and retired to the waiting room for a coffee. Before the machine had filled the cup a guy came in and told me it had passed. I said “that was quick” to which he replied “they had been too frightened to touch it”!
