It seems it was first sold as Formula 27 F 27 KR.
I think the F 27 KR/Monza was an enclosed bodyshell placed on the chassis of the F 27 Lotus Seven replica. Later all the Formula 27 projects moved on to YKC and then Image Sports Cars (where it was renamed Image Monza). It's confusing as it was made by three separate companies in the space of a few years. About ten years ago I had some stuff sent to me by YKC about their model range at that time. There should be some stuff on the F 27 KR there.
