Some funny stuff out here lately.
There's a person selling a vintage York that is pretty beat up and missing the swivel lock bar for $75
Heavy York vise - tools - by owner - sale
Heavy older work vise in need of some love. It’s big and sturdy. $75seattle.craigslist.org
Then there is this person:
GLWS I guess?BENCH VISE COLUMBIAN 6" MODEL 206M2 BAB - tools - by owner - sale
This is a unique and hard to find giant vise. It's like new, weighs 160lbs and is the mother of all vises. it is 27-3/4" long, 15-1/4" tall with a 10-1/4" footprint. Made in the USA. You have to see...seattle.craigslist.org
That vise is a Yost, not a York. I think any 5" vise that isn't welded or otherwise damaged and under $100 is a pretty good deal. That one shows a little wear in the pictures but overall looks like good condition.
@FARMAN33 you sure like the big vises. Another nice specimen, not sure where you find them. There is a Wilton 800 posted locally but I thought his price was a little crazy. Maybe not though, not sure on those 8" Wiltons.
