The backhead is beautifully laid out; platework is neatly formed and fitted; paintwork is bright and presentable, if not to the exhibition quality of the rest of the build.\u003c\/p\u003e\u003cp\u003e    The engine rolls freely although currently doesn't run on air. It tries, but there is leakage past valves and\/or pistons that will need the valve chest covers removing for investigation - not an uncommon problem in engines which have been laid up for a long period.\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54019803545941,"sku":"11756","price":2950.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/11756-1.webp?v=1779907424","url":"https:\/\/stationroadsteam.com\/products\/3-12-inch-gauge-maisie-4-4-2-stock-code-11756","provider":"Station Road Steam","version":"1.0","type":"link"}
