The 'missing' Junkers engine projects

[Nick Sumner]

Jumo 214, 215, 216, 217, 219, 220, 221.

Anyone got any idea what they were?

Take a look at this forum`s thread "Argus As 412 and 413 engines ". To add some more stuff, the Jumo 216 would sport 2 coupled Jumo 206. There was a further Junkers project to mate two Jumo 205. Nothing else on the others.
