Until very recently in fact the company slogan was "Dependable Dorman Diesels"; when an American diesel concern complained some years ago that this was a crib from their own slogan which they had used since 1950, Dorman's were able to reply that they had been using it since 1935.
Another popular feature of Dorman engines was the efficient after sales service that went with them, which many customers were pleased to testify to, this again is a primary advantage available to the Dorman customer of today. In those days, as a veteran
Dorman service engineer has reminisced, "field service", might more often then not be literally carried out in a field on ones back under a diesel in six inches of mud and rainwater. The layman might well be forgiven for the contrary impression so easily derived from glancing through trade magazines, that all diesels squat photographically in the middle of tiled rooms.

In other fields, Holman Brothers of Cornwall had an established precedent of
using Dorman engines in their compressors and other equipment which endures to the

A formal licensing arrangement by Dorman did cover the foreign manufacture of the Constantinesco interrupter gears in the thirties; ironically the foreign concern involved was the Imperial Japanese Government. Fortunately (at least for this history) Japanese aircraft design had advanced, by 1941, beyond the point where Constantinesco gears were actually required.
We are now able to look at one of the most interesting periods of Dorman history; the general adoption by a wide range of manufacturers of Dorman petrol and diesel engines for all types of industrial and construction uses. This was a process that had been continuing with gathering acceleration since the end of the 1914-
