Thank you for your reply.  The rear axle displays "Oliver" on one side and "Rowcrop" on the other.  THanks..

O. K that means it was built somewhere between 58 &amp; 63. Next question. Do you have factory power steering. Also look by the generator and see if a number is stamped in a flat spot which would be the engine number. They went to that location in 61. Before that they were stamped on the right r3ear engine flange. I will be gone for a week so don't expect a quick reply.[/quote:3fopjxll]

John, again thank you for your reply.

Looking over the tractor yesterday, I believe I do have factory power steering.  The PS pump and generator are back-to-back on the right-side of the engine.  The generator does not look original, but the PS pump does.

There are no numbers on the right-side of the engine.

The tractor has a wide front axle (not a tricycle).  On the rear axle is printed "Oliver" on one side and "Rowcrop" on the other.  The engine is a 6 cylinder gas.  The transmission has three forward speeds and one reverse.  I can not find any mechanism for low/high on the transmission to double the speeds.  The carb, air cleaner assembly, and starter are on the left-side of the engine.  The distributer and generator/power steering pump are on the right-side of the engine.  There appears to be a tachometer connection under the distributer that is currently not hooked up.

I can not find any model/serial number plate anywhere.  It may have been on the dash as I see holes in the dash where is may have been located.

Here are the numbers that I can find:

Engine, left-side rear (in top to bottom order):

	185220F
	104306A
	2170

Carb (metal tag attached to float bowl bolt):

	Marvel Schebler TSXU-836

Clutch housing, rear face:

	101467A

Frame, right-side rear in front of axle:

	101472A

What confuses me is that the literature I have says a 770 has 6 forward speeds and 2 reverse.  My Oliver only has 3 forward/1 reverse.  I not sure if this tractor is suppose to have a low/high selector on the trans.  I can not find where a lever connects for this purpose.

Again, I thank you for your time and efforts in helping me identify my Oliver...
