Since Massey Ferguson didn't open their Brantford Combine plant until early June 1964 and the Company only became Massey Harris Ferguson in 1953, I was wondering where the likes of the MH # 20 & MH # 21 combines were  built ?
 i had read somewhere long ago,  that the MH # 20 had been built in Batavia or New York - which one is correct ?

Good question, I googled it and diddn't get a good answer on the model 20 but they said the 21 was built in Brantford, Ontario.  In my younger days I ran alot of these machines, there is a 21A still sitting in my yard along with several 82s, a 27, and a Super 92.  I thought I was somewhat knowlegable on the combines but I came across a Super 92 Diesel listed with an A6.305 Diesel 6cyl engine tucked under there. I have seen 6cyl Diesels in simular machines in England but never in the US. At first I thought it was a misprint but it is listed on the Serial tag so must be factory. I think this is kind of a rare bird.  Here is a link to the auction it is on. Any thoughts or comments?
