Went down to the shop this afternoon and wanted to see what I really had. The handle would barely turn, just dry and dirty. I kind of lubed it down and have got it to turn with one finger now.
It was a handfull to pick off the ground and set it up on the pallet/bench. Next time I'll let the forklift down, it didn't look that heavy.
So what's the deal with the swivel? I have a nut on one side, the other side just looks like a "button". Do I have a broken off stud there? or is this how they're made?
I also took some more pictures with a reference for size, I see most guys put a pop can in the picture, I couldn't find one, but the 1 gallon paint can, maybe is more size appropriate.
Just because I'm curious, how old would this be? Is there a serial # anywhere on these?

That is a one good looking vise.
As ragtop explained the "button" is part the very effective and neat brake mechanism that parker used (akin to a drum brake in a car- see the photos which should help visualizing this mechanism). I have a Parker 204 (Pat 1910) which has a single split shoe with a prominent fixed bolt to anchor the shoe to the static housing (see photos) . In the latter models the shoe is double split with a hinge on one side (see photo from my 974).
So again as ragtop explained your vise is in good shape and there is nothing wrong with it. By the way I think CP 436 weights around 185 lb so you did good lifting it

.
As for the age, I have seen CP 436 with Pat 1930 but yours does not seem to have the Pat date, so it might be from late 1940, early 1950s (my guess).
