Thanks, Finn, that's interesting. After I read your post, I tried looking up one of Tracy's, and it says 'unknown'. I like 'vague', if I can make it fly. ;-)

Anyone else have one to share?

Question for you guys who've registered your rotary powered a/c in the USA.
Is your 'type of engine' simply 'rotary' (could be confused with Le Rhone, etc) or 'reciprocating', or 'reciprocating (rotary)', or...?

For the engine 'manufacturer, model and serial number', did you use 'Mazda', etc, or your own name/model/etc, or something else?

Many thanks,
