Congratulations Gil. 

I just arrived home from two weeks in the bush with no internet or cell service.

This was the first post on the forum I looked at this morning.

Two very nice stirling engines. 

Do you know who built them?

What a couple of amazing machines!

That first one has a truly marvelous motion .... what would you call that, a broken beam engine or possibly split beam, hinged beam, counter beam ... or???

Whatever you call it, by any other name, it is amazing!

The second one obviously uses a pair of air-cooled cylinders as the basis, and a sort of modified form of a Ross yoke, I think, to link the two engines together. Lycoming aircraft cylinders, motorcycle cylinders, something else entirely type of cylinders .... who knows??? I sure like the slow speeds that it is capable of maintaining!!!

Yesterday's auction found me arriving home ready to rest after a long day.

I was able to acquire several interesting Stirling Cycle Engines.

Here are the first two.

Enjoy!
