LBSC maintained a  correspondence with Robert Riddles, designer of the prototype, which led to him  producing 3 1\/2 inch designs for both this and \"Britannia\", somewhat  of a coup at the time, as he was able to provide \"Model Engineer\" with  a construction series for \"Britannia\" the month the prototype first  rolled out of the works. 75000 was serialised in \"English Mechanics\"  during the time of his big fall-out with \"Model Engineer\" - whether it  was due to the smaller circulation of that magazine, or other designs firing  people's imagination, there have been relatively few of these built over the  years; this is the first one we've had in.    \u003c\/p\u003e\u003cp\u003eThis is a new, unsteamed engine. Although not built to any kind of exhibition  finish and with a paint job that is long on gloss and short on masking tape, it  surprised Steve and I when he ran it on air in the workshop - it goes very well,  a free-running chassis with good solid exhausts. The silver soldered copper  boiler is by John Ellis, quality as is you would expect from a man who's made  not far short of a thousand boilers over the years. Working pressure 80psi,  three element flue-tube superheaters, feed by axle pump and injector with a hand  pump in the tender. Gunmetal cylinders, piston valves actuated by Walschaert's  gear with screw reverser in cab, mechanical lubricator. Most of the cab fittings  have been liberally covered with overspray, it's the first engine we've had in  with a gauge glass in grey primer...    \u003c\/p\u003e\u003cp\u003eIt will need some fettling before use, certainly the cab fittings could use  dismantling, cleaning and putting back together again. There will undoubtedly be  a variety of \"new engine\" tweks required - glands packing, pipework  leaks fixing, all the usual stuff - but there is potential in this to make a  good looking engine.    \u003c\/p\u003e\u003cp\u003eLength\u003cbr\u003e  Locomotive 31 inches\u003cbr\u003e  Tender 18 inches    \u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003ccenter\u003e\u003c\/center\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54019821535573,"sku":"5009","price":2350.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/5009-1.webp?v=1779907748","url":"https:\/\/stationroadsteam.com\/products\/3-12-inch-gauge-br-standard-class-4-stock-code-5009","provider":"Station Road Steam","version":"1.0","type":"link"}
