I picked up a rusty Columbian Vise D63 1/2 today. My questions are: Should this vise be Red? Looks like it was red or orange and then someone painted it green. Most all the paint is gone some I'm going to refurbish it. Can you take the split ring keeper off of the main screw without it breaking? This vise doesn't have screw on jaw plates, is there a way to date it? Is there any other information I should know about it but didn't ask? TYIA, Steve. Oh, it only cost $4.
