Looking for scan-with-ruler, measured drawings, the actual article, contact w/ the developers, etc.

Last set I've even heard of was a ROL auction ages ago. Still worth trying :)

I would suggest contacting Doug Pratt and Pratt Hobbies and see if he can point you to other leads.

Reached out to Doug Pratt and a decade-old-plus listing for Marcus Leech.

Hope I'm not pestering too much in my quest for hybrid injector knowledge.
