C Parker bench vise Model 0 or C
 

I am trying to find out some history of this bench vise. It is designated as C but someone suggested it may be a model 0. Either way I can't find out any info on C or 0. I don't have a need for this vise but wanted to find out what it may be worth.

Most Parker vices are readily available and are not bringing any high prices. Most are purchased as used working vices and priced between $25 and $100. I have a fairly large one, similar to yours pictured that I purchased at the Syracuse Farmers Market for $25. Its an excellent vice and I use it almost every day. It is currently holding a Farmall Cub cast iron exhaust/intake manifold for painting.
