On the subject of Allis tractors, they were very popular here in Australia. Nearby to here there are quite a few unrestored units including a KO crawler with a gaping hole in the crankcase after a minor explosion from inside, several M crawlers, 2 early 'round bale' hay balers, a c1927 E? motor, and many common-or-garden farm varieties including rowcrop. Have photos if you're interested Regards Robert
