[R-390] Re: r-864 questions

[Dave Merrill]

Hi Don,

Thanks for asking about the R-864.  I took a few better quality 
shots of the interior for your examination:

As you see, the PTO is a 70E-30 which is the next in sequence in
70E series according to your list.

Every few months I get an inquiry, but as far as I know, only one
example exists.  The serial number is 2 so maybe #1 is out there?

I wrote to Warren Bruene recently and he was nice enough to send 
a 2-page letter with his speculation on it's origin.  I've posted 
it along with the photos.

73,
