Tom,

I've no idea whose that tractor is but there are a handful of 201s, 202s, and 203s over here with very odd ones having been vandalised (!!!!!!!!) by putting a Perkins engine in them.  Of course these would most likely have been done for economy when they were working rather than recently - it would be nice to see people change them back to original Chrysler of Contiental engines which I am sure could be picked up in N America
