Just to sort things out a bit...
This car is a YG2S6 (BMC code YDO21) and called the Mini 1100 I don't think they came with chrome strips around the door but I am not certain. (can owners of other YG2S6 tell us more)
The Mini Clubman was YG2S7 (YDO22) (had chrome around door frame)
The Clubman GT was YG2S8 (YDO23) (had chrome around door frame)
These models were replaced by the Leyland Mini range and the Clubman name was dropped. The cars were upgraded a bit in quality, no more centre dash speedo and no more magic wand sedans.
YG2S6 became 021A2S1M10 and called Leyland Mini (No chrome around door frame)
YG2S7 became 022A2S1M10 and called Leyland Mini S (had chrome around door frame)
YG2S8 was not replaced.
