Hi Nick, Thanks for that. I had glanced at it but thought it too small but with your comment I looked further and it could be the No 5 1&1/2 HP with parts of the valves missing. Arnie Ferro got a picture of a smaller one. I will send the post below to the Ausie lad.
---------------------------------------------------------------------------------------------- British Engineers and Electrical Company Leek Staffordshire.
In 1905 a number of design changes were made after which a few changes occurred. A No 4 engine of 1 HP at 500 rpm was brought out In 1906 and followed by a No 5 of 1 ½ around 1911.
The British Engineers and Electrical Company supplied the majority of the engines in kit form to various companies and home engineers who undertook the machining and assembly
In such situations various modifications would be made to suit
various needs or applications.
It is these modifications that make identification so difficult!
Arnie Ferro took a picture of a small one at the 1000 engine rally.See
