22 machinist vise with swivel base and adjustable jaw. This is the generic/house brand/unbranded variety of No.The vise casting marked on the top of the stationary jaw, just behind the adjustable jaw and reads "PRENTISS NY" on first line and No. 22 on bottom line - see picture #4.
Marked "P V CO" below the main screw head (handle), see pic #5. Also has a "619" mark in rectangle shape on base (see pic #6). The "619" is interesting because it would be a reasonable month/year for manufacturing date.
Prentiss didn't make model 619 that I'm aware of and component matching numbers were typically two digits. Permanent jaw style with moderate to heavy wear but still some scored jaw face surface remaining. All I've done with this vise since I acquired it is rough cleaning and inspection - dirt, grime and loose paint removed with manual wire brush and compressed air.
No penetrating oil or other chemicals were used for cleaning or adjusting the vise swivel, jaws or screw. Most recent paint was gray, original paint may be the light blue showing through or could have been all the way to black. Some light welding splatter and dings/ridges in jaw area. I've inspected this big boy from every which way and there are no cracks visible to my eyes.
The most common spot for cracks on these old Prentiss models is the slide and that component appears to be undamaged and no repairs visible. This vise is in working condition and both the base swivel knob and adjustable jaw tapered pin are present and working free and easy. The handle is straight and true.The jaws close smoothly and evenly - at full close the jaws align side to side and there's possibly a 1/32 gap on left end due to uneven jaw faces. Overall condition noted as "very good used condition" - "very good" is reasonable based on the age of the vise, full function of jaws, swivel and pins, absence of new/old damage (cracks) with less emphasis on cosmetics. What you see is what you get and there's not many examples in this condition floating around these days!
