[R-390] General Info R-390A

[Dennis]

Thanks for the input from all.  And Roger, good details on the mechanical stops.
 I did some filling, cleaning, and moving some of the brass shims around and all seems to perform well now. The shims were in rough shape causing tuning to be fairly rough. Hopefully, this will smooth out the bad spots.

On another note: gear clamps, I am waiting to hear back on some numbers and info. A distributor in Raleigh, NC said that Berg makes many different types and sizes, as well as gears for other applications. 

Great group here for such a large part of history!
