Wilton makes three "Bullet" vises...
The Tradesman, the Machinist, and the combination series...
The photo will show you the size difference between the Tradesman and the Machinist...
The Combination is "sort of" in between the two, and has pipe jaws which the machinist does not...
Good vices...Everybody's "gee, I want one of those", is the 500/600/800 Machinist, and the C2/C3...
But they are never, or almost never, cheap...
The vise you have there, is a Tradesman, which is a bang up home use vise...Will do 95% of the things you need a vise for, so if it's not priced in thr stratosphere, get it...
