For the record I do know the difference between a rotary and radial engine. On the other hand I have *no* idea how that happened. Senior moment. And thanks for the nice comment about the article.

Derek, you are one of the few who can determine the difference between a rotary and a radial. And in this case you are right, it’s a radial not a rotary. We figured someone would get around to correcting us!
Thanks for reading VT…

Surely, by 1929, it is a radial engine, is it not?
Thank you for a fascinating article, nevertheless.
