@Robert S. Butler and @FRENCHTRAINS thank you both, very much, for your help! I questioned it mainly due to the lack of raised lettering but also due to not being able to find, initially, a shell like that which had four, separate and spaced strips of rivets without any other detail- such as the gold bands in your photos, between the rivets.
As luck would have it, I did come across another similarly sized Tin German Locomotive with tender and the Loco has an electric motor! While not in working order, I’ve never seen a motor like it(although one of my repair guys has). Will post pictures when I get back home.
Thank you, both, again, for your help !
