Watch your spelling. Locked for you till your next reply

I'm sure that's the spelling my source has, but apparently others call it "Rhemag."

(BTW, I seem to be finding conflicting info regarding the city as well.)

[Allemano]

Rhemag is correct! 
The company which produced this car was called Rhenania Motorenfabrik AG of Berlin and Mannheim.
Cars of this type were only built between 1924 and 1926 in the Mannheim factory.

BTW, I have a pic of this car in a book (which, as I said, calls it "Rhenag") that's actually the same pic, but with the background detail grayed out and the glare on the window removed.

[Allemano]

I have two quite reliable book sources with two different pics. Both call it Rhemag. One of these apparently shows the same pic you've mentioned.

Found that the car is named as "Rhemag" in another book I have. I've now noted the correction in the book that says "Rhenag." Once again, AutoPuzzles exposes an error in what I thought was a reliable source.

I find it hard to believe that Rhenania Motorenfabrik AG  would use Rhenania Motorenfabrik AG rather than Rhenania Motorenfabrik AG.
Parallells with DELAG (Deutsche Luftschiffahrts-AG come to mind.
