They are advertised in my 40s magazines.

Have you run it?

Hi,
I don't have ANY first hand knowledge of these motors. IIRC, I believe that Brown made them. I seem to remember an article in a British Model Magazine that showcased the man and his work. A brief bio.

Very cool. Is it complete?

I didn't know they made them so long ago!
They might not be the smallest anymore though:

It is complete as far as I know.

I have not tried to run it, but my little brother did put the original co2 cannister in (against my wishes!) but I was so mad at him i forgot to ask if it worked...

Had a look through some old mags today, and found the Campus mentioned in Summer 1950 (June, July, August.) model Aviation magazine---the one put out by lan Allan.

On page 26 there is a pic of a 15in span Dick Korda Powerhouse, built by J.H.Maxwell, powered by a Campus CO2 engine.
On page 46 the article tells us J.H.Maxwell scaled down from the drawings in a 1949 edition of model Aviation of the Powerhouse to suit the Campus.(l have these plans)

He says it flys well, so must assume that the model at 15in span, the motor must be small, and can only guess it's at least from 1949.
