Here is a picture of a 6231A that has GMC truck and coach, Spicer, and Brown lipe all on the same tag. I have yet to see one with Watson on it as well, but it's possible, as Spicer ended up with them all.

About different brands being only OD or only underdrive. I don't believe that, as I have seen some of all the brands mentioned above that have been both ways. And I find that the majority of Spicer branded ones are made as OD units.
What I have not found is a Fuller that is overdrive. I have a few Fuller auxiliary transmission manuals, and all of them are direct and under. I have also searched for an OD fuller auxiliary, but have yet to find one, leads me to believe that they may not have made an OD auxiliary.
