[TR] [Fot] GT6 Alternator

[TR3driver at ca.rr.com (Randall)]

It means except a "Mk I" GT6 (except of course it wasn't called "Mk I", just
"GT6").

And that is because the early ones had a generator instead of an alternator.
If you look earlier in the book, I think you'll find the generator section
marked "GT6 only".
