The Camber GT and Maya GT have been covered extensively here with articles on every car known to me. 'NPM 14F' was a bit of a mystery for some time. Back in 2011 there was very little known about it with only two sketchy pictures in the files (here). But not long after that I learned the car survives and was sent a few more pictures (here).
I spoke to the car's owner before who told me he'd bought the kit directly from Camber boss George Holmes and used it as a daily driver for several years. He made a trip to Germany in the car in 1968 or 1969, remembering it felt pretty small on the autobahns in between all the big BMWs and Mercs! Originally it used the 850 engine of the Mini that was used as a donor, but after a few years this was replaced by a 1000. Another couple of years on and it was time to fit a 1300 with race cam and big valved Cooper 'S' head!
I also learned the Camber had had various colours in its life. Originally it was red, but at one time it became gold with a yellow stripe when people started naming it 'the Banana Split'. The car still needs a comprehensive restoration.
