Ian , Looks like someone has spent a lot of time on this.
Yes, I did
Looking carefully the size of the horn should have been a clue to the scale
It's 4" scale (4" to the foot, so a third size)
Then I looked at the number plate, 2008 plate, but its black, have the boys in blu stopped you yet, and out of interest what does the log book say, and does it have an SVA?
It's registered an agricultural tractor, so doesn't need a front plate ( also dosen't need an MOT. One day I'll take it to a testing station just to see the reaction

). I have a proper black on yellow rear plate for when I take it on the road.
Peter, yes it's fully functional. Quite happy pulling 3 or 4 adults ( or a trailer load of kids!) around the rally field. I do have to remember to use the right fuel. Coal in the engine, petrol in the Mog. I'll get it the wrong way around one day
