^Made by millers falls. Very easy to clean up in that shape. Where did you find this I’ve been trying to find it again ever since it was originally posted a few months ago.
I got the 150mm from a GJ member in 2014 and the others came to me locally. It's funny how it goes. When you work on vises they seem to migrate up to my place. I get calls all the time with good deals and people needing cash.
New topic here, I hope I'm not interrupting anybody's conversation. (as a side note, why don't we get a separate vise sub forum? it would make searching a lot easier too.)
I have never seen a vise like this one, it looks like the inner jaw moves, and is supported by ways. Does anybody know who might make it? And what do ya'll think about the condition, how hard would it be to clean up?

Thought I would post a few pictures of my Rock Island 594 has a date stamped 449. I would think Sept of 1944. It also has a stamp that is half ground off. Looks like USN.![]()

Morning folks, need a little assistance with a vise that’s for sale as I know practically nothing about Prentiss and have been scouring here and elsewhere on the net but am running out of time so asking for a little info and guidance. The vise is a Prentiss 6” swivel jaw, and that’s all the info I have other than the picture. The markings are on top at the back of the swivel which I believe makes it an older model, possibly a #22, but that’s all I know, other than I’m questioning the base and wondering if it’s missing a swivel or is it as was when left the foundry. Oh, yeah, price. Ha ha, ok so this is the most I’ve even considered spending on a vise but I’m wondering if this is a decent price for this size with swivel jaw or not. $200-250 depending on if the stand goes with it or not so $200 I guess bottom line but have to talk to seller again to confirm. Interested in hearing some input/thoughts y’all might have. Thanks in advance. -Josh
Kwoswalt, Thanks for the ID, this guy was in Birmingham. As soon as I posted, I knew I needed to go get it, so I did. Payed $150 for it, weighs about 190 lbs, or so I was told.
Most of the rust is superficial, but it is locked up pretty tight. The "ways" are really a rectangular groove (you can see this on the right side of the pic, but not really on the left), which the inner jaw slides in, and I think they are rusted together. The nut/screw may also be rusted tight too though. Unfortunately the seller had it out in the open uncovered, at least when I was there to buy it.
I'll post some pics when I get it out of the car, and as I get it cleaned up.

The one I have has no model number on it. My base is newer with round holes and a different locking lever. I like the square holes and handle !
Thanks for catalogue Getridaone, information is this vise or Millers falls seems a bit scarce.
I managed to get the nut off without too much hassle, but the dynamic jaw is still stuck in its groove. I have been encouraging it with WD-40 and a 2x4, but so far its still stuck tight. An suggestions on freeing it up? Here is a picture of the bound up groove.

Gman, You are correct in your observation that the dynamic jaw insert is slightly taller than the cast iron jaw, not sure whats up with that. Both the inserts match each other, and the static insert matches the static jaw, but the cast iron dynamic jaw does not match its insert. The original picture makes this look a bit exaggerated, because the corner of the jaw is slightly rounded off, but you can also see it in the pic above. Interestingly the width of the jaw (same as the insert) is 6-7/8".
Heres a picture of the new one next to my now petite looking 4" Yost.

It isn't even bolted down!OK, The mash gauge came in today, and I have some preliminary results for 3 of my vises. I have to do some "setup" for other vises, and I may need to have someone help hold the table down to get to full capacity, as I lift to get max tightening as I'm only 170 lbs and 5'7", so I could stand on the handle and not get there...
I did learn a couple of things right off the bat:
- The key grease point is under the head of the main screw
- Lithium is NOT a great high pressure grease...
- I used some 30 year old cam assembly lube and got much better results
I mentioned I lift to tighten. I was also hurting my hands, so got a pair of heavy gloves. This and the cam lube jumped the numbers by 20% or more...
Lift to tighten was no problem on my bench mounted Parker. Lifting to tighten on the American Scale I started to lift the table. The table is a steel rolling bench that has to weigh over 200, and the AS weighs 137 by itself, there are other things on the bench so well > 300 lbs... (admittedly I didn't lift the whole bench, but it was up on 2 wheels, and the vise was clamped onto the lifted edge... Not bad for a guy "past his prime")
The real surprise was my new to me Allmatic mill vise. It has a torque multiplier, and it blew off both my everyday 4" Parker (9" handle) AND the American Scale 6" (with 13" handle) and it did it with... (Drum roll) a 2" twist grip!It isn't even bolted down!
I'll get more vises setup over the next few days, and see where some of the others land, but as mentioned, I'll use that steel bench and it needs held down.. (Long bar across the top and someone leaning on that...)
Here is the list, in order of the "force" produced:
And a pic of the Allmatic:
- The yellow highlights are because the Parkers Royce tested were all over the map, and I found that interesting, and in one case I was not positive of the jaw width.
- I have added data in the new columns to Royce's where I could get there.
- The handle length on my AS is in red as I don't know if the matched the length to the original
- Handle lengths are measured from the center of the main screw.
Again, these are preliminary, I have more to go...

Yost, The only advise I have for you is keep at it. Rust seems to be the worlds best glue for snug fitting metal parts
gman, My vise has that similar looking mold mark in the same area as Yost's vise. It appears to have held up fine while the jaws were being destroyed. Looks to me like the welding was to fill in behind the replacement jaws on my vise.

Nice data there Outlaw, if you want consistently then I would be happy to build a fixture that clamps on the handle over the meatball with a 1-1/4 hex or so where a torque wrench or a long cheater bar could be used for the same pull or push. If the owner of the pressure gauge can wait. I already see a fixture in my head that would work and not hurt any of your vise's handles. The grease is a must in my opinion. Kind of fun to do stuff like this. It would be interesting to see how a Wilton PowRscrew vise compares since it has the hydraulic Piston and claims to have 3 tons of clamp force. I do not think your Allmatic with the torque multiplier is built the same but maybe.
Picked up a unicorn last night. Might be my new favorite vise.
Hollands 53 1/2 H
93 lbs. 4-1/2” jaw width. 5” opening. 5” throat depth. Reversible pipe jaws. Swivel base that isn’t a thru bench

That is a great idea! I’m happy for my little “mash” gauge as Outlaw named it to continue its adventure for a while longer.
Looked this Reed 404-1/2R over today during a recreational shop crawl. Owner asking $245. Thought I’d share the eye-candy.
I sold one on EBay in perfect shape and it had Wilton 3 1/2" jaws and it only went to $75.

Outlaw, how does an Almatic work?---Similar to a torque wrench?
