Warford Secondary - Educate Me

[LFEngineering]

I've done a little bit of searching and I didn't really see any pictures of this particular model Warford secondary transmission.

I have a few questions:

How do you remove it? I've never had the pleasure of working on early Ford closed drive shafts; Any pointers how to take them apart?

Anyone have an info on this model Warford?

Anyone every seen one in the wild?

Based on how super low first gear is already, I'm hoping its an overdrive transmission. I'll need to pull it out of the chassis and spin it on the bench to find out.
