Series Gear box ID

Hi every one,
Just found a series gear box in my container, i have no idea which series it is out of.
I know it's not a S3 box the clutch linkage is on the driver's side, the serial number
is 23600762 A.
Any info will be greatly appreciated.

Thanks Steve, that thread is very helpful.

No idea on serial nos.
But if box has round tin cap its slightly later, early ones had a removable cap with spring clip to hold it closed.
Early tfer boxes had a really small level plug compared to later ones, and you had to fill them up via the plug op top of the box located in the blank plate.
