This un-built 4mm. scale kit of parts for a Johnson MR/LMS 0-4-0ST locomotive may require some other parts of choice for completion. However, the kit of parts has three different sets of wheels and axles which will allow construction in different gauges, one set of which has been painted. Included is un-used Mashima motor in good running order and an un-built High Level SlimLiner Compact gearbox, two sets of different frames, a set of made-up hornblocks, set of whitemetal body and cab parts including an etched brass cab front/roof. There are two different sets of Alan Gibson sprung buffers, and sets of coupling rods, frets of coupling/buffer parts and detailing parts. There is a set of Keyser construction instructions with an exploded parts diagram and a Precision gearbox building leaflet.
