Twerts: i'd buy the red one for $50 and blast all that red paint off and find a spot for it. i'd probably take off the bench top which looks like an add on and sell or keep the vise depending on what it is.
I've seen some of those cabinets for sale on my local Craigslist for $400 so even if you don't have room for it just clean it up and sell or trade it for some tool or cash.
i'm guessing military for the red cabinet.
The carburetor cabinet is interesting, but not very useful unless you have a need to store small parts. i do like the patina and the cool name and condition, but open drawers with Plvmb printed on it would get my money.
