Can Anyone ID this by looking at the gears? M20, M21 or M22?

The two lines on the cluster gear would mean M20. Does it also have two lines on the input shaft?

No lines, fine spline.

That's an M20 wide ratio. Count the teeth on the input gear. Should be 21 teeth which identifies it as 2.52 to 1 wide ratio 4 speed.
That's a replacement input shaft which was available with no spline identification or "rings" located on the spline.
