It looks like a Warford, but it is smaller and has no markings on it. I think it is just an under drive, but I don't own it; so I haven't tore it apart. I am just trying to help out a fellow T'er.
Is it a transmission or a power take off? These are all side shots so it is hard to tell.
shifter looks like a later mod or perhaps it was a remote shift moved onto the box - that would make it a diff mounted box though
It's a Woodward. Direct and underdrive. There should be a name plate on the side of the shift lever, unless it has been lost.
