Thanks Raphael. I also conclude that it is not a model of a paddlewheel steamer engine but was certainly inspired by one. I do have this model of a side lever paddlewheel steamer engine. It was modeled after the French Navy's fist steamship "Le Sphinx". Made by a modeler in Germany but missing parts of the valve gear which I need to make. Unfortunately no drawings.

Bonjour,

To my opinion, this is not a paddle steam machine, the crankshaft has only one side. The flywheel is builts for this machine furthermore?

Below an example of paddle steam machine :

Was wondering if this model engine has any resemblance to a paddlewheel steamer engine? I can't think of any other reason it was inclined (mounted diagonally), although it obviously has a single flywheel rather than twin paddlewheels. Most of it is made from brass castings (nickel plated) and thought to be from the 1860s-70s. Any thoughts? Just the imagination of the maker?

Runs nicely on 3-5 psi air.
