EMC E2A/E2B electrical gear?

What original generator and traction motor combination was installed in these early EMC E units? Was it GE or Westinghouse?

Looks like it was all in-house electrical gear, unlike say the GE traction motors under Rock Island's TA's.

The E1 and E2 used the GE 5GT544 main generator. The traction motors were GE716 or EMC D7 traction motors the D4 main generator was first placed into the FT and E3 with D7 traction motors in 1939. The E1 and E2 were built in 1935 thru 1938.
