Not a lot is known about the engines produced by Latimer Products of Latimer Road, Teddington, Middlesex, England. They produced two models in the years immediately following the second world war. There was the small L4 and the much larger and more substantial L5. Curiously the two engines shared virtually no common components.
Latimer Products engines were sold under the name "Plane Models".
The Latimer L4, with its horizontal boiler and vertical cylinder, has an unusual layout for a British made engine. Another novel feature is the combined chimney and safety valve, which also acts as the boiler filler cap. It is quite a small engine, the boiler is about the same size as that on a Mamod Minor 1.
This one was in good condition when purchased and has been left as found. It is complete with the original burner.
