I was able to but this engine on the dutch website marktplaats.nl. I paid 120 euro for it, and with that there was even a flatbase flineshaft included.
The enginge has a unusual boiler, there's only one end cap, and that's not in the traditional mamod style either.
The engine is in need of a full restoration, for one or another reason, there's no paint left on the baseplate at all.
There's also some soldering work to clean up, the union nut is soldered onto it
