We sold this one back in 2015, it's just come back in with the Avery undermount traction engine as part of a rationlisation of the owner's collection of projects.

  • Broken boiler mounting bracket laser welded into place
  • Boiler tubes unblocked, then all tubes cleaned
  • Boiler internals descaled
  • Boiler tested and new x2 hydraulic test certificate issued (21/04/2019 ).
  • Boiler reassembled with new Kaowool boiler lagging fitted, cladding cleaned
  • New O rings on all 3 R A Barker clack valves
  • Regulator cleaned and reassembled using new PTFE washer and O ring
  • Blow down valve cleaned
  • Safety valves cleaned - need resetting before steam test
  • Water gauge cleaned and reassembled using new glass and O rings
  • Pressure gauge cleaned, red line marked, and gauge tested during boiler hydraulic test

A 3 inch scale steam wagon, based on an Atkinson but with conventional twin cylinder slide valve rather than the more complex design of the prototype.

The engine has been running recently - last outing was running for three days at the Harrogate Show.
