A well-made Burrell Gold Medal tractor to the M.J.Engineering design - it's come from the builder who, having completed it bar some minor jobs and run it a few times some years ago, was distracted by other projects leaving the engine unpainted. Quality of build is such that it would be worth stripping and painting - it runs very well.
Silver soldered copper boiler, 120psi working pressure, feed by twin injectors with an auxiliary hand pump in the belly tank. Twin cylinder compound, slide valves actuated by Stephenson's gear with pole reverser. Two road speeds, gears commercially cut, supplied by M.J.Engineering. Canopy is built in mahogany.
Work remaining includes plumbing the lubricator up and making a lid for it, making boiler cladding sheets and completing the governor.
For inspiration, I've had several good examples of this design, there are pictures of a particularly good one in the archive.
