I bought this box of bits a few years ago.
I didn't know quite what to expect but was nicely surprised when I arrived home and "propped" it together.
All of the the main items seem to be there. The No.s seem to suggest it is a early '30s Grass or Dirt track engine..ie.Methanol.(from Jeff Clew)
The only puzzle is the lack of mag drive provision? Perhaps from the primary side maybe although I only have one photo of the use of this arrangement. Think I may be being a bit dense here?
