[R-390] R-390 (non-"A") production data?

[frankshughes at aim.com]

Hi,
I have been Googling around looking for production data on the R-390, no luck at all.


Comparatively vast amounts of good info on the "A" all over the place, but I can't seem to hit the magic
search phrases to find out how many R-390's were produced and for how many years.


I know someone here will have the data!


Thanks,
Frank
