The J/B and 101 (‘57 ~ ‘61)
The ‘J’ type was updated in 1957, with the fitting of the O.H.V. 1489 cc, 42 bhp, ‘B’ series engine, mated to a 4-speed box. Chassis numbers, starting at 36,266, carried on from the earlier ‘J’ type but were now prefixed with JB/MR (B series/Morris). To distinguish it from its predecessor, the van became known as the Morris ‘J/B’. Not until the advent of this and the Austin version of the van did the ‘Morris~Commercial’ front grille badge give way to the larger ‘Morris’ one.
Other websites, including Wikipedia, have claimed that, after 1952, ‘Commercial’ part of the name was dropped and the van was marketed as the Morris J-type. This is patently not the case. Although the ‘rise and fall’ Morris~Commercial lettering gradually disappeared from sales literature for the J-type, the word ‘Commercial’ was clearly carried over until well after the J/B was introduced. The ‘Morris’ badge only appeared after 1957.
The Austin 101 (‘57 ~ ‘61)
Badge-engineering by the British Motor Corporation saw an Austin version of the J/B introduced, known as the Austin ‘101’, which differed from the J/B only in the design of the front grille panel and the badging. These carried chassis numbers in sequence with the J/B but prefixed by JB/AR (B series/Austin) so it is impossible to work out how many of the Austin version were produced.
Production ends
Production of the J/B and the 101 ceased early in 1961, although vehicles were still being registered as late as December of the same year. The very last van produced carried chassis number JB/MR 48,621, which allows us to state that approximately 12,355 J/Bs and 101s were made, but the separation of these figures into Austin and Morris quantities can never be known.
Approximate production figures for J-types, J/Bs and 101s combined have been worked out by the Morris~Commercial Club, using data from period Glass’ Guides:
1949: 750 1950: 5,347 1951: 5,051 1952: 4,098 1953: 5,027 1954: 6,000 1955: 6,894 1956: 3,169 1957: 3,284 1958: 3,131 1959: 2,965 1960: 2,516 1961: 362
In comparison, the Volkswagen Type 2 (commonly known as a ‘Splittie’), produced between 1951 and 1967, had a production run of 1,853,439 – over 1.8 million more than the combined production run of J-types, J/Bs and 101 vans!
