The series began with a 495 cc iteration for the 1930 Datson Type 10 and ended with the 860 cc Type 10 engine which was built until 1964 for light commercial vehicles.

Later versions were called the B-1, before being replaced in 1957 by the OHV Nissan C engine that was essentially a de-stroked version of another Austin design this time the BMC B-Series.

The displacement of the original version was kept beneath a half litre since driver's licenses were not required for such cars after a ministerial decision of 1930.

Postwar cars again claimed 15 PS (11.0 kW), at 3600 rpm.

This engine was called the B-1 when installed in the 1958-1964 Datsun Cabstar; this version produces 27 PS (19.9 kW) at 5200 rpm.
