I'm glad you got the Inpro LTD engine working Daniel. I do recommend the Kontax ones though, they do cost a bit more but are worth it IMO. I'm certainly considering another one of their high temp models to go with my Nano Mason. 

I’ve been fascinated with the Kontax LTD assembled low temp KS90 I purchased after my Nano disc horizontal tungsten. They make a nice pair in my showcase and running in tandem on display.
The LTD mechanical actions are all as smooth as silk, and it truly will run from the heat of my hand. Superb design and build quality.
They are a definite grade level above a “toy” , and they impressed all the M.E. & E.E. and Aerospace engineer friends I showed mine to. The fact that many models come with a free real glass dome case, have free worldwide shipping w/tracking, and some models even offer customized 3 lines of engraving and those Kontax are a real collectors’ value . Higher price yes, but excellent value.

 Sadly it will be very hard for such a quality independent small Machinist & Engineering company to face the mighty onslaught of throw-away level cheap-cheap Stirling toys made by slave and near-slave foreign labor.

I’m now desiring a Kontax Ross or Rhombic , while Kontax still survives.
Yes , Swift Fox —— they are worth it !
