The HB engine was a 2 stroke Diesel Engine made by "Cummins Diesel" that was in production from 1936 to 1946.
These engine's powered many things including Trucks & Buses and even some generators.
It main production and use was during World War 2.
For this engine, It was imported into Australia and use by the Australian Defence Forces,

Info From DWM:
Cummins had a somewhat incomprehensible engine nomenclature system in the early days.
It started with a basic one letter engine model series identifier, such as “H.”
To that could be added more designators to further define the engine’s intended purpose.
In the earliest days of the H series diesels, adding a “B” indicated an automotive application, e.g. “HB.”
The HB standard build-out often included automotive-style mounting points, water pumps, flywheels, a generator, bell housing, and possibly a fan all subject to the customer’s needs, of course.
The “BI” (“I” for Industrial) was the so-called “mobile industrial” engine (e.g. “HBI”).
They were intended for a variety of uses, including heavy off-highway such as graders, cranes, or crawlers.
They could also be used in stationary jobs.
Some might include a few automotive-like features but most likely would be built to match a customer’s specification.
As stated in "wikipedia":
The Cummins Engine Company was founded in Columbus, Indiana on February 3, 1919 by mechanic Clessie Cummins and banker William Glanton Irwin.
The company focused on developing the diesel engine invented 20 years earlier.
Despite several well-publicized endurance trials, it was not until 1933 that their Model H engine, used in small railroad switchers, proved successful.
The Cummins N Series engines became the industry leader in the post-World War II road building boom in the United States, with more than half of the heavy-duty truck market using Cummins engines from 1952 to 1959.
In the 1960s, the company opened an assembly plant in Shotts, Scotland (closed in 1996).
By 2013, Cummins had operations in 197 countries and territories.
