Ref #18 the first one is the Atom Minor Mark 111 first produced in 1933 mine is not that old can`t remember the date but you will see in the photo`s where i bought it from you just bought the castings and the book and away you went and glad to say mine worked it would swing a 14"x5 prop but 12"x6 was more recommended and being petrol it had coil ignition setting up the timing was interesting and the rear induction kept your fingers away from the prop. I made it round about the time glow plugs came out so it`s not that old.
The second one is a Canadian Bantam and the serial number dates it to 1947 again another petrol engine i don`t know how many model aircraft engines there are maybe 200 or more but i would rank this engine within the top 5. The photo`s don`t do it justice the casting is superb along with the workmanship a real gem of an engine. Have just read that in the American Model Engine Encyclopedia it is Bantam #7 never knew they were made in America if it is the same engine either way it`s areal beauty.
Lastly some of the books i was brought up with
