John,
I like the French Cub it looks in good original condition. Was that taken at your local show yesterday that I said I might come come down to?. If it was I wish I had since I'm missing an air clearner top and I might have been able to get dimensions of that one in order to try making one or fabricate a look a like for someone to make in metal. I didn't get to the show I intended on Saturday since it poured rain alll down. It cleared up by lunchtime on Sunday so I went across to Stonehaven but it was only for cars buses and motorcycles on the Sunday.
On the M that must be a diesel engine that was put in. The chrome exhaust stack doesn't look right for that tractor otherwise nice.
