[R-390] 390/390a gear train

[Flowertime01 at wmconnect.com]

Joe Foley ask any chance anyone would like to do CAD drawings
of the gears and cams?

Page 50 figure 30 Tuning system, simplified mechanical diagram of TM 
11-5820-358-35 has a fair cartoon of the gear train for the R390A.

How about we get someone to do a good scan or photo of that figure and get up 
on Al's R390 page. 

Could we find the equivalent one for the R390?

But then if someone wants to go into history as the Fellow that did a CAD 
drawing of the R390 gear train here is your invitation to immortality.
