Widely-regarded as the first close-to-scale drawings produced for  a model traction engine, Hughes had access to the full-size engine in the 1950s  (an engine now in preservation) and produced a highly detailed design which  remains extremely faithful to the original. Written up in the \"Model  Engineer\", Hughes subsequently published the construction articles as a book.\u003c\/p\u003e  \u003cp\u003eAlthough often tackled by newcomers to model engineering attracted by its  modest size, the design calls for a considerable amount of experience to build  successfully, both in the ability to tackle complex individual parts and also to  cope with the sheer quantity of bits - basically if it was on the original  engine, it appears on the model. As a result of this, I see a good number of  Allchins which are not all they could be(!).\u003c\/p\u003e  \u003cp\u003eThis model is better than 90% complete. It has a professionally-built  silver-soldered copper boiler by Alec Farmer of Reeves fed by mechanical pump on  the second shaft and injector (not included but widely available from the usual  suppliers). Three cock water gauge with blowdown, 0-160 psi pressure gauge. Two  speed with differential and back axle-mounted winch.Platework for the  tender and boiler cladding is very neatly done, with fine rivetting.\u003c\/p\u003e  \u003cp\u003eRemaining work includes:\u003c\/p\u003e  \u003cul\u003e    \u003cli\u003eGovernor\u003c\/li\u003e    \u003cli\u003eGear guards\u003c\/li\u003e    \u003cli\u003eBrake gear\u003c\/li\u003e    \u003cli\u003eFit and plumb up injector and water lifter\u003c\/li\u003e    \u003cli\u003eComplete mechanical lubricator (tank made already, pump body to do)\u003c\/li\u003e  \u003c\/ul\u003e  \u003cp\u003eThe chimney base flange has been cracked and a piece lost - it could either  be repaired by silver-soldering in a piece of metal or a new base made which is  a simple turning job.\u003c\/p\u003e  \u003cp\u003eThere is a box of parts and castings, including the governor body,  professionally cut governor gears, formed steel tyres for front wheels, spuds,  machined drive pins, boiler transfers, \"Royal Chester\" nameplate.
