Nut, FZ,
the black cabs, were procured at the instigation of Sqn Ldr Brian Tiller who as MT2a could see that Brampton were at times sending 2 cars to the railhead, often at the same time to collect pax. The taxi holding 5 was ideal so eventually Brampton had 2 of them. They became commonplace, and IIRC we had one at Gut, was often used to take the staish to functions where he wanted to reinforce his "Britishness".
When the Nissan engined variant appeared in the middle '90's it was clocked at 90 mph on the A1 (I had to deal with the speeding ticket that appeared)
