Number of speeds on early gearbox

Hi all,
a friend of mine is offering me for sale an early gearbox that was parted out and sold to him years ago. We are not sure whether it is a 4 or 5 speed gearbox. The numbers that appear on the casing are:
Top: 901.301.301.OR
Bottom: 902 / 1 3280227

Would somebody please help me identifying its year of manufacture and number of speeds?

Assuming it is a 5 speed, the shift pattern would be like this?
R 2 4
1 3 5

Finally I would appreciate comments on its market value assuming it is not refurbished but in good condition.

Thanks in advance for your help,
Rafael

902/1 is 5 forward ratios, AFMSX, shift pattern is correct

902/1 is a 5 speed with some good gears AFMSX
used in 911 65-67

Thank you for your comments.

I decided finally to have my gearbox repaired instead of buying the one I was offered. Synchros are fine. I only need to replace the bearings that were making noise.

Now that my gearbox is out, I confirmed that the number stamped on the casing is: 901/07 7190082

According to an article I found on the Web, I believe this box belongs to a 1969 911E or 911S. I have found no information on the gear ratios.

My car is a 1969 911T. The engine is 2.2 with Weber Carbs and E cams.

Would someone please provide me with the gear ratios for this box and comment whether this box and gear ratios is appropiate for my engine?

Thanks in advance.
