Pratt & Whitney 6" vertical shaper

All that is mentioned in "manual" is the rotary, which turns out to be 90 to 1 - one turn of hand wheel being 4 degrees

Fairly sure one can use that 90:1 and the numbers on the index plates to determine what they can do

For instance on that plate

Index Plate Calculator

I got a nice long list of possibilities using your numbers on the plate, 90 degrees and the display option

It looks like that machine had a recent Chicago job on the saddle. Make sure the ram has some flaking for oil. Lots of sliding contact there. Its not hard to pull the ram from the machine for a tune up.
