Thanks Nick and Bruce.
I never thought I would end up with all four of these.
And impressive that Gil owned three of the four at one time.
Now I need to build (have built) a proper cabinet for the four of them.
The hot air engine was also owned by Gil at one time.
I guess all roads lead through Gil when it comes to rare Toy Steam Engines. 🤠

I don't know if it will ever happen again..... Your Marklin Stirling Cycle Engine actually self-started one time only!
