New and unsteamed, it comprises a small side flue boiler with coiled water tube,  connected to a most unusual little engine. Can't see how it works - indeed would  have been more than happy to say it can't work except that, if I blow into the  boiler, the flywheel goes round. The cylinder has a slot down one side with a  peg screwed into the side of the piston. The end of the pen ends in a ball,  which engages in a matching socket in the propellor shaft. So far, so good, the  conversion of reciprocating to rotary motion is ingenious, but what has me beat  is how the steam is routed around the (double acting) cylinder - I can't see how  the valve works.\u003c\/p\u003e  \u003cp align=\"left\"\u003eAnswers on a postcard please...\u003c\/p\u003e  \u003cp align=\"center\"\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54020059398485,"sku":"2905","price":90.0,"currency_code":"GBP","in_stock":false}],"url":"https:\/\/stationroadsteam.com\/products\/side-flue-boiler-and-engine-stock-code-2905","provider":"Station Road Steam","version":"1.0","type":"link"}
