Hi Cal,

The Fiat built Olivers are also the same as some Allis tractors such as 5040, 5050. If you do some searching you'll find that there are several other tractors that are also Fiat built or quite similar. 

There is a fellow in Canada that deals in parts for the Fiat built tractors. His e-mail is: <!-- e --><a href="mailto:oldtractorsspam@renc.igs.net">oldtractorsspam@renc.igs.net</a><!-- e --> , take out the spam. I believe that is the correct e-mail. Good luck, WB.
