Some call it a solar engine, others hot air engine, I prefer to call it by it's inventor a Stirling engine.
Today a Bing Stirling arrived and it was in pretty good condition some dust and dirt over time but that is normal.
Only the burner house and chimney suffered from some surface rust, so that had to be cleaned and the steel re-blued.
This is how it was advertised…
The red bace plate was something to loose first.
The complete engine was taken apart to give all the parts a good clean.
After a reassembling and oiling this was the result…
Than the function test…
And finely a group photo with "the Guarantee".
A similar engine wit different print.
Both at work…
Cheers,
Danny
