Thanks to our good friend Crab Fu, and his friend Indiana Rog, I am able to bring this (unfortunately-named) German company to your attention. These 100% handmade (no CNC, even), spindly-yet-sturdy amalgams of brass and glass would be a bargain even if they were inanimate. Stationary they are NOT, however! Mr. Rog’s YouTube video shows that they are indeed the efficiently whirring devices one would hope them to be. I think one of these engines would look just as comfortable chiffing away on a Victorian tinker’s workbech as it would on the shelf of a certain wizardly headmaster…

Oh, and please do check out Mr. Rog’s website! You will find it a wonderful resource, no matter if you’re a serious model engineer or simply enjoy photos of gleaming mechanations. I would devote an entire post to it, but I don’t want to over do it with the engine articles…

edit  As Copper Sulphate kindly pointed out, I forgot to actually link to the Wiggers site! It would be here. ::Slaps forehead::
