Found Oliver in Barn, Help Identify

It runs, good rubber, has hydraulics with front blade (Narrow Front,) side curtains, some surface rust, no holes. 6 cyl. gas., 38 inch rear tires.

It looks like a Super 66 or 77 but I'm not experienced enough to tell the difference.

How do I tell what model it is? Is there a tag somewhere? I found a brass tag on the front blade assembly (Oliver).

Do I dare ask what the street value for these are worth?

Thanks for your help,
Mark

It sounds like you're describing a Row-Crop 77 HC. These were six cylinders with side panels and hydraulics. The serial number id plate on these tractors is on the right side of the final drive case directly ahead of the band brake cover. On those models produced during and after 1952, the brakes were disk brakes (cast cover) and the id plate was moved to the lower left of the instrument panel near the hydraulic unit. Once you have the serial number, a White dealer or one of us here on this site will be able to tell you exactly what it is and when it was made. P.S. Since it is a six cylinder, it could also be an 88 but the id plate will still be in the same locations as described above.
