Pretty sure it's Stuart, it's a large  compound launch engine. There are a pair of cylinder standards, I would have  expected two more. There are no cylinder blocks, but there are end covers,  showing the large LP and smaller HP bore size, valve chests with Stuart covers,  four well-machined eccentrics, slide valves, heavy seven-inch diameter marine  flywheel and a large collection of sundry bearings, eccntric straps and  miscellaneous castings.\u003c\/p\u003e    \u003cp\u003e\u003cfont color=\"#FF0000\"\u003e2nd October - One of my resident Stuart experts has  been on the telephone to identify this as a Stuart 6A  launch engine. There were only two cylinder standards, the cylinder block bolted  atop with pillars down to the bedplate like the No.1. A large engine, rated 4  bhp at 750 rpm on 120 psi steam. Capable of driving an 18 to 22 foot boat.  Drawings and castings still available from Stuarts - the full set of castings is  currently listed at £1470.\u003c\/font\u003e\u003c\/p\u003e    \u003cp\u003eFull specification and a picture of the completed engine on \u003ca href=\"http:\/\/www.stuartmodels.com\/inprod_det.cfm\/section\/casting\/mod_id\/57\"\u003eStuart's 6A page\u003c\/a\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54010007290197,"sku":"2109","price":30.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/2109-1_ca20583a-3be8-4362-8b6c-e842a18e7f1a.webp?v=1779899919","url":"https:\/\/stationroadsteam.com\/products\/set-eccentric-straps-stock-code-2109","provider":"Station Road Steam","version":"1.0","type":"link"}
