Unknown Toy Steam Engine - Doubleacting Oscillating Piston 

Finally after a couple of weeks soaking in penetrating oils, i managed to free the piston on this "rarity".
Have no idea of the manufacturer, but strongly assume that it was made in Denmark, seing that they tend to pop up for sale here now and then.
This one came without flywheel and burner, but with a very nice base, boiler, and firebox.
I just made a very simple brass flywheel (way too heavy), and threw a standard Mamod 3 wick burner under the boiler, to get it tested.
