I recently spotted this John Ericsson engine on a dutch auction site. I thought there would be a lot of things wrong with it, since I could buy it for only 41 GBP.
I think I got quite a bargain, because the engine was totally complete, burner, box safety valve,chimney and whistle where all there. The engine is also in a quite good state. Some paint is lost and some pieces are rusted, but nothing major.
This is what the engine looked like when I got it:
It's quite a sophiosticated engine, a lot off small pieces and everything is nice screwed together (no pop rivets),It even has 5 settings on the reverse lever:
I thought the burner was missing, but it's very clever hidden:
The engine is quite big, look at this comparison with a mamod SE3:
The boiler is not spherical like you might think, take look at these pictures from the box:
I have to say that this is a very nice engine, very good build quality and a lot of great details!
