Part 3
Thanks for the comments and compliments - Here posting another photo, and I have two more also.
The previous owner said that he had run the engine on air, but it still needs some adjustments which I have not gotten around to yet. I hope to maybe even get it going on steam in the Spring, after I sort out a testing bed, and for that I will need to work oudoors with it, no safe place to try inside the house (no fireplace!).
I have only seen one other example, and it was also being sold out of England. The other one had the same basic tank, but most of the engine itself was a much more modern replacement. So far I have been unable to find any photos at all of any types of steam spitjack engines, although there are some brief mentions of them in accounts of spitjacks in general. In contrast, there are heaping piles of illustrations and accounts of the earlier mechanical spitjack engines.
Will follow up with the remaining photos.
