Built with four screw cylinders!
But it is such a late model otherwise, I have to wonder if that was done by Jensen or ...... ?
Whatever the story may be, that is one very cool difference, and should make for one very powerful steam plant!!!
Yes! Good eye!
I was told by the seller that his father bought the engine new. So I am assuming it came from Jensen Mfg that way.
The thing is, you can’t just steal two four screw cylinders from a couple 25 models and put them on a 55. One of the cylinders has to be a mirror image of the other one.
True that!
But well within the capability of many machinists to invert a steam chest on one of these.
Still, there seems no limit to the wonderfully nonconforming material that has leaked out of Jeanette PA over the years!
I'd have to think that if it is a one-off (or extremely limited) Jensen product, there would likely be some form of notation on the bottom of the baseboard?!?!
Custom Order? Prototype?? Perhaps of Extra-Terrestrial Origin???
