[R-390] R-390 History

[JamesMiller]

I have heard that serial number tags were often replaced during depot
maintenance, so the tag on your radio is probably not the original anyway.
Likewise, the modular design meant that depot repairs could be done by
replacing entire modules... over the life of service, I would wonder if a
given radio even has its original modules.
