Doesn't the one in Lincoln have a huge hole cut in it, so the inside is visible?
I was kind of surprised to discover that the Fosters factory had gone. I grew up near Lincoln, and still have family close by, and have driven past the site, noticed the new retail park, but not noticed the factory is gone. How strange ones perception can be.
I think they went down to Bovington to meet the current RTR and have a charge around in a Challenger (as well as seeing the museum).
I thought one of the best bits was when they first fired up the engine - the guy from JCB just looked so happy!!
