the MY-TE was basically a automotive-type generator that was used as an electric motor. I do not think $50 was over-priced, as long as its all there.
Used to know something about the Oliver-built Wizards but I forgot all that stuff, except that it "might" have Scintilla coils in it…
Hope this helps.

He's livin' in his own private Idaho..... I hope to go out quietly in my sleep, like my grand-dad did..... and not screaming, like the passengers in his car...
