3 inch scale Allchin agricultural engine - stock code 10184

A well-advanced 3 inch scale Allchin agricultural engine by an experienced model engineer - older readers may remember his 2 inch scale Fowler A7 which we sold in 2009.

Work to date is to a high standard, we'd put the project at better than 90% complete. Work to complete includes:

  • Gear guards
  • Boiler cladding
  • Reach rod and lifting lever for weighshaft
  • Safety valve bobbins and spring bar
  • Boiler fittings, including clack valves and injector
  • Make and fit water pump
  • Paint

Rear wheels have been fitted with strakes, with steel bands over should it be desired to fit rubber tyres.

Not common in this scale, we've had a few over the years, including a super one by a friend of ours - now sadly no longer with us - which also had a John Rex boiler; there are pictures and further information about that engine in the archive here.
