I purchased this in the late 70's - it's been in a heated garage ever since.
2nd design - 1" counter shaft diameter.
2.43, 1.61, 1,23, 1.00 close ratio (1.5, 1.3, 1.2 drops approximately) 2-groove input
No corrosion of the aluminum case because it still has original grim, oil, dirt & kept in heated garage.
The gears are sharp nub teeth on all the gears.
The forks are hardly worn: 1st and 4th are not even into the middle wear pattern.
Gear box lube looks ready to go - no trace of moisture.
Date Code Feb 1976
