I don't know how it compares to others either, but I have a PM66 and use several old ones at work. I don't have a photo but that same perspective seen on a 66, all you will see is motor and trunnion....miles and miles (or should I say pounds and pounds) of trunnion.
A lot of trunnion. Nothing but trunnion. Very stout trunnion. Seriously large heavy trunnion. Big baldor motor too, with an interesting cast iron yoke mounted to....a massive trunnion. Did I mention it has a large trunnion?
You look in the cabinet and all you can see is a giant black iron box, you can't even see the blade or arbor, just the trunnion....
