An old model which has languished in a shed  for the last twelve years since being bought as a \"winter project\" by  the previous owner.\u003c\/p\u003e  \u003cp align=\"left\"\u003eThere is not a great deal of work left to be done, it is perilously close to  being a running engine. The chassis goes well on air, the silver-soldered copper  boiler is plumbed up to the cylinders, although without superheaters (for which  there are flues in the boiler). Some boiler cladding would be an idea, the thin  coat of green paint all over the boiler - including the backhead - probably  won't do much for reducing your coal bills (as well as looking revolting). There is an axle pump fitted and plumbed,  drawing water from the copper saddle tank. The cast iron cylinders are fitted  with slide valves actuated by Hackworth gear with a pole reverser on the  footplate.\u003c\/p\u003e  \u003cp align=\"left\"\u003eAlready quite a large, heavy engine, when finished it will be  around three hundredweight and with similar performance to a \"real\"  Wren - there are several \u003ca href=\"\/products\/stock%20pages\/3119\/index.htm\" target=\"_blank\"\u003ein  the archive\u003c\/a\u003e, including a couple of nice ones which sold this summer  (although not before Sam and I had a chance to try them on the railway at home).\u003c\/p\u003e  \u003cp align=\"left\"\u003eLength 39 inches\u003cbr\u003e  Width 16 inches\u003cbr\u003e  Height 32 inches\u003cbr\u003e  Driving wheels 6 1\/2 inch diameter\u003c\/p\u003e  \u003cp align=\"left\"\u003eBore approx 2 inch\u003cbr\u003e  Stroke 3 inch\u003c\/p\u003e  \u003cp align=\"center\"\u003e\u003ca href=\"update.htm\"\u003e\u003cimg border=\"0\" src=\"thumbnails\/Wren-005.jpg\" width=\"300\" height=\"242\"\u003e\u003cbr\u003e  April 2009 - now running\u003cbr\u003e  \u003c\/a\u003e\u003c\/p\u003e  \u003cp align=\"center\"\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54010060964181,"sku":"3190","price":3250.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/3190-1.webp?v=1779900217","url":"https:\/\/stationroadsteam.com\/products\/7-14-inch-gauge-part-built-wren-stock-code-3190","provider":"Station Road Steam","version":"1.0","type":"link"}
