William:
I came across that document when I started out filling in an old K & D set finding lots of parts at Larry’s. You probably already knew that though. 
Later,
Tom
P.s I happen to have a large color photo of a complete K & D 18 Inverto that was sent along with the set. If you need a copy, I can scan it next week when I get back to work. It shows many of the parts/descriptions/etc. that you may not be able to find from the PDF. At least the decals are still intact.
