{"product_id":"stuart-hb6-steam-plant-stock-code-12167","title":"Stuart HB4 boiler \u0026 compound twin steam plant","description":"A large steam plant, comprising a gas-fired Stuart HB4 boiler with compound twin engine.\u003cp\u003e\u003c\/p\u003e\u003cp\u003e    In size and proportion, the engine is similar to the Stuart offering, although with reverser detailing reminiscent of the John Bertinat designs; it's complete with displacement lubricator, drain cocks and a gear driven boiler feed pump. We like the valve chest pressure gauges - suspect from the diameter of pipework that they're ornamental rather than functional, but a nice detail.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e    The plant is mounted on a substantial polished wood and aluminium base plate. There's a water tank and hand pump with bypass valve to one side, with a gas tank and oil separator - the latter currently not piped up - on the other.\u003c\/p\u003e\u003cp\u003e    The boiler is missing the cover plate from the far end of the central flue - a simple part which could be replaced by a turned component.\u003c\/p\u003e\u003cp\u003e    Fitted with a simpling valve connecting HP to LP valve chests, the engine runs on air in one direction, reluctant the other way.\u003c\/p\u003e\u003cp\u003e    Complete with a propellor shaft and propellor, overall it makes for a handsome, impressive-sized model.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e    Free UK shipping included.\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54019838804309,"sku":"12167","price":1495.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/12167-1.webp?v=1779907843","url":"https:\/\/stationroadsteam.com\/products\/stuart-hb6-steam-plant-stock-code-12167","provider":"Station Road Steam","version":"1.0","type":"link"}
