Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Okay, this thread is back alive as I have unlocked it. Somehow it seems I locked it a few days back, but didn't mean to do so.

I am looking for anybody's input that can help provide details on the Inception, Evolution and History of this iconic model Stirling Engine, and the companies that made, advertised and marketed it. As posts come in, I will glean info from them and transfer it to the dedicated early posts at the top of this thread.

Eventually, or sooner, this will all get moved to the "Toy Steam, Scale Model, and Antique Engine References" Board, but for now I want more people to see it and hopefully respond with good information .... PLEASE.
