I have more than 10 vises, but it is hard to keep track.

They are spread out over several workshop areas and vehicles. Even some in storage.
Machine Shed: 6" China, 4" Columbian D44-M3
Workshop: 5" Columbian 3050, 4" Parker non-swivel
New shop: 6" China rotating/swivel, 4-1/2" Parker on welding table
Shop trucks: 2 6" Harbor Freight China vises, 1 small table vise on a 2" stinger
Pipe vises: Rigid 3" Bench mount, Rigid chain Tri-Stand
Collectors: Cheney Vise/Anvil, Versa-Vice (New in Box)
Drill press: 1 Wilton 4" tilting, 1 China 6" tilting
Milling Machine: 1 4" Taiwan, 1 8" USA, 1 Jet dividing head
A couple of small table top vises, one is a vacuum mount.
I'm looking for a 6"+ American-made vise, but the collectors around here have bid up the prices beyond what I can afford.
