Hi,

I'm looking for a good source on different German propellers covering desginations, design features, basic measurments etc. Especially Junkers propellers, clarifying the difference between Ju PAK, Ju HPA, Ju HPB, Ju HPC.

We've got on German landing gear designs so why not one on propellers!?

Suggestions on sources would be appreciated!
Thanks
