Greetings everyone!
I am relatively new to this particular forum, not new to forums in general in the least.
I acquired an old vise from my Welding Instructor that is need of some serious TLC. Can't complain one bit though when it was free! I'm having a hard time identifying which model it is in particular, which is keeping me from hunting down some replacement parts. I'm hoping someone on here might have an idea or is able to point me in the right direction. Onto some information and pictures--
The vise is a monster. The Jaw width measures 5". I'm not sure on how far it will open. The upside down U shaped washer is missing and I cannot separate the two jaws without a new one, hence my dilemma. There is no visible "Model #" that I can tell, but there are what appears to be Part #'s(?) on each piece.
You can see the main missing part here:
I was able to disassemble the vise slightly, removing the inner spindle parts as well as the back dust cap. Here are some closer detail pictures on the only visible numbering.
I believe this reads "101042"
This side reads "101043"
The spindle assembly reads "101041"
The underside of the bottom swivel reads "101081"
My goal on this vise is to do a complete restore so it functions just as well as it did on day #1 and to keep it in the family for a few years. Based upon what research I was able to accomplish, my guess as of right now is that it might be a 70's-80's 500s model? Again, I'm not 100% sure. I don't want to order any replacement parts until I have an idea of what model it actually is. And since I can't get the two jaws to separate, I have no way of checking the date stamp on the key. Any help anyone could offer would be greatly appreciated! I do intend on documenting the complete restore once I'm able to begin.
On a side note, this vise lived outside in the elements on a grinding booth. You can't tell in the pictures above, but there was a SERIOUS layer of metal shavings that had built up over the years and stuck to one side of the vise. I was able to chip a lot of it away, but the largest section came off in one piece.
This is rough look of how it sat on the one side:
Once I was able to remove it:
The piece that came off probably weights a good 2-3 lbs.

If anything I think it helped shield the vise from the weather and what not. Pretty neat I think.
Thanks,
Scott
