The catalogue of 1970 showed renderings of a British Class 33 and a Mark IIB coach in blue-grey. In 1971 and 1972 these models were not pictured in the Lima catalogue, but in 1973 they were back again. Lima then made a Class 33 and three different Mark IIB coaches in H0 scale 1/87, ignoring the tradition of OO scale (1/76) in the UK. These models looked small to their British counterparts, and they had continental hook and loop coupling.
To my knowledge the first series of the 9137 was a 1st/brake only, it's hard to find.
1976 marks the last year these models were produced. The entire British outline was switched to 1/76 scale in 1977 and the range of H0 models was dropped. Remaining stock was sold in starter sets.
