I did a quick search through a few web sources and could only find it identified as a “New Process” 5 speed transmission. Typically found in Chevy Big Bolts, including school buses. I have a 1967 big truck Chevrolet Illustration and Parts book that says it was used in 1956-67 vehicles.

I imagine it has a model number, but my quick search didn’t locate it.
