Question about a Sherman Transmission

I have one question, what do I have on the attached photo. I assume its a Sherman transmission. If it is a Sherman, then can you tell what kind of Sherman it is by the photo.
Thanks for your help.

Is it 2 positions?
It looks like mine, which is a step up.
Lever forward is factory gearing, back is step up.
 
Since both used the same handle it's either a step-up or a step down sherman trans. Can't tell which one by
looking at the handle. Since it's an 8n pop the steering box and look inside red= step down grey= step up.

There are 3 common Sherman's The step up or also should be called an over drive. The step down or under drive or the combo. The combo you shift it to neutral and pull out side ways then back up for the standard gear it would have if it did not have a Sherman in it

What do you mean by a step up, does that mean that the gears are higher?
 
When you drive it from a stopped position pull the handle back towards the operator, If it speeds up it's a step-
up, if when the handle is pulled back and the tractor slows down it's a step down. pushing the handle forward is
the standard gear range.

As said, the step up and step down Sherman's used the same handle.
But, since the step up is about 10 times more common than the step down, if I was a betting man I would lay odds you have a step up.
Which brings up the question; it's pretty well known that the Ns had pretty fast ground speed - especially in reverse.
I wonder why step ups were so much more common than step downs which I think was a more useable transmission?

here to there stuff
no safety police back then UD.
Watching the old guys that live around me flying down the road
between fields......whew..N brakes...worn steering...they don't care. lol
also, since N's seem to always get the light mowing duties.
maintaining proper PTO rpm without the engine screaming was probably attractive. Example, I finish mow a couple acres of yard with a Farmall Super H...handles it easily of course. I could drop the rpms quite a bit and that engine wouldn't labor, but I need that proper pto rpm for the mower. wish it had a step-up.
