The first (and only) advertisement for this engine appeared in Model Airplane News of June 1938 in which it was named merely (and I quote from the ad) "..an Alternate Firing Twin". It could be ordered direct from Southern Model Engineers of Nashville Tennesee for the sum of $20.00, postage paid. The engine was the work of Bob Chunn, a barber by trade, but a talented modeller with a love of machines. Today it is most commonly called the "Chunn Twin"
