>Is T-47A/ART-13 a legitimate nomenclature?

Very much so.  It is the USAAF's improved version of the Collins
auto-tune ATC transmitter.  The various nomenclatures run as follows.

ATC           -   USN.    Transmitter, made by Collins.

ATC-1         -   USN.    Transmitter, but IIRC, made by another outfit.

T-47/ART-13   -   USN.    Transmitter, same as ATC but with JAN
nomenclature.
                          When matched with AN/ARR-15, becomes part of
AN/ARC-25.

T-47A/ART-13  -   USAAF.  Improved T-47 for USAAF service (AN/ART-13A)
                          Used with BC-348 (AN/ARR-11) to make AN/ARC-8.
                          Most not made by Collins.  Principle
improvements are:
                          (1) VFO (Dial B) vernier scale allows
frequency setting
                              at 1 kHz intervals all through frequency
range.
                          (2) Top lid dynamotor control power cut-off
interlock.

T-47A/ART-13  -   USAAF.  CDA-T oscillator unit installed to allow 20
MF/HF and
w/ CDA-T                  4 LF/MF crystal-controlled channels.  (Early
AN/ART-13B)

T-412/ART-13B -   USAAF.  Same as above, but with MF frequency extension
switch
                          to allow operation down to 1.67 MHz.  (Later
AN/ART-13B)

17H-2         -   Collins commercial model (same as T-47).

My favorite version is the T-47A/ART-13.
