Hi agn,
I found it -- Donnie's list. It's just for the R-4A's, but he points
out the differences between the 2 versions. I seem to remember, and
Garey can probably comment better, that there were some more small
changes made toward the end of the "late" version, such that the very
late ones were about the same as an R-4B.
Take a look at

Yes, the R-4 series all are the same serial number string.
The R-4 started at 100 (I believe, I've never seen one below that). The
first schematic is labeled '0001'.
The R-4A started at 2000 with the 13 tube version.
The R-4A continued at 4054 with the 11 tube version.
The R-4B started at 7000
The R-4C started at 16151
The R-4C ended right around 30000. I've heard of 30k+ s/n units, but
I've never actually seen one.
The T-4X started at 10000
The T-4XB started at 13749
The T-4XC started at 20181
The T-4XC ended just over 30000. I've seen a couple with 30k+ s/n.

the "plain" r-4's are included in the series below the R-4A no.s.
Donnie Garrett had a good listing of the s/n's for the R-4A's, but I
don't know where it might be available now, he dropped out of
circulation a few yrs ago. Anyone know?

Do the R-4 receivers share the same run of serial numbers, the R-4's
the lowest and the R-4C's the highest?
