I have a Chas Parker 995 vise. It is rusty and hard to read the names and numbers on the side. The crank handle is also rusted, but with a little jiggling, it does move from end to end through the crank. The vise does open and close all the way but it does tend to be a little hard to crank in a few spots. I would like to know if this vise is worth more in the condition it is in or would it be worth more if I cleaned most of the rust off of it. I have seen these sell on Ebay for up to $500 and maybe over. Any idea what this may be worth in the rusty condition and in the clean condition. I don't want to do anything to it until I find out which condition is worth more money. I no longer need this vise and I am looking to sell it.
