Robert,
Sorry I don't have the driver transformer. Unless I decide to part out one
of the several SP-200 series that I have (if anyone is looking for one,
contact me). You might look at what AES has available (www.tubesandmore.com).
It appears that the Signal Corps bought a lot of civilian marked Super
Pro's, mostly 1942 and later, and never put nameplates on them. One of the
photos in the October, 1944 TM 11-487 shows a radio ID'd as a BC-779 (the most
common model) that does not have a nameplate. Your receiver is a BC-1004. All
that I've seen did have nameplates, though.
