Help!  I just bought a farm that had an Oliver 77 in the barn. It has a row crop front end--serial # 3 510 518 on the plate with 77-3565 under that. I was told that it is a 1953. It is a diesel. There is another front end in the barn, too, which looks to be a standard or adjustable front end. Several #'s on it ---1035 427  726  1K-72.   The question is does it belong to the Oliver 77? One message I read said that Standards weren't made in 1953. Any help would be appreciated!  Thanks.
