Is this a 3-speed or a 4-speed '49 Ford truck transmission? (pic)

I've got this transmission removed from a 1949 Ford parts truck. I'm still confused if it's a 3-speed or 4-speed. My shop manual confuses me with their parts diagrams for all the various available transmissions, and the cases are very similar.
What do I have here?
Thanks in advance...
Oh yeah...the arrows in the picture are of the wear on the teeth. I'm also not sure if there is any life in those gears.

4 speed, all straight cut gears, no syncronizer for second - third.

 

Thanks, that was what I was hoping for - to match the F2 it is going in.

Now...does anyone think the wear on the gears is anything to get concerned about? I've put some arrows in the picture to show the wear areas.

Thanks again,
Tom

 

Nothing wrong with the gears pointed at, most transmissions I have been in look like that. It's called chamfer I believe. From what I know, it makes it so the gears "roll" into place when shifting instead of sliding. But that's just hear say.
