{"product_id":"3-inch-scale-marshall-traction-engine-stock-code-2361","title":"3 inch scale Marshall traction engine","description":"\u003cp align=\"left\"\u003eAn example of a rarely-modelled prototype, a 7nhp Marshall using  Brunell Models drawings and castings. This designs builds up into a big, strong  engine - six inches longer than the ubiquitous 6nhp Burrell and getting on for a  hundreweight heavier. It makes a very capable rally performer, similar in size  to some smaller four inch scale engines.\u003c\/p\u003e  \u003cp align=\"left\"\u003eSteel boiler with expanded tubes, 100psi working pressure, test  certificate to September 2005. Removable manhole. Feed by mechanical pump with  bypass and injector. Slide valve cylinder with Stephenson's valve gear with pole  reverser on footplate. Mechanical lubricator driven from valve rod.\u003c\/p\u003e  \u003cp align=\"left\"\u003eThis is a three shaft, two speed engine with winch mounted  behind the left hand rear wheel. It has recently been stripped and painted and  is generally in good mechanical order, although wear in the valve eccentrics  could use taking up (and the injector has a mind of its own).\u003c\/p\u003e  \u003cp align=\"left\"\u003eApologies for the artifically-lit pictures, the engine's in the  workshop and, at the end of a long day, it looked far too big to drag outside!\u003c\/p\u003e  \u003cp align=\"left\"\u003eLength 54 inches\u003cbr\u003e  Height 33 inches\u003cbr\u003e  Flywheel 13 inch diameter\u003cbr\u003e  Rear wheel 19 inch diameter\u003c\/p\u003e  \u003cp align=\"center\"\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54019767107925,"sku":"2361","price":5800.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/2361-1.webp?v=1779906935","url":"https:\/\/stationroadsteam.com\/products\/3-inch-scale-marshall-traction-engine-stock-code-2361","provider":"Station Road Steam","version":"1.0","type":"link"}
