Weaver Auto Twin jack sale on Denver Craigslist - not 100% complete - missing two casters and crank handle.
Seller says if she doesn't receive an offer by this afternoon that it will go to a scrapper.
You can probably get it for much less than her listing price.

I hate when people use that ploy, they may let it go for scrap but a lot of times it's a ruse to get a bite. KB
