Peter, it was in Vols 130-131, in 1964-65. Edgar Westbury originally mentioned it in 1940, in a series on hot-air engines, but those articles just contain the drawings (incomplete) with no details. I have been told that the mid-60's articles contain full build details, so may have some useful information.
