Where are you Zoomie?---Your not looking at that one.---Zoomie needs a PM.
Earlier today I indicated I was waiting. I was waiting to hear back on my first Prentiss vise. I don't actually have it yet but my brother-in-law picked it up for me this evening. I'll get it next time I'm up in DFW area to visit family. The jaw pads need to be replaced for sure and at least one of the pad bolts is broken off in the jaw. The handle has a little bend in it. My BIL said he could see no welds, no cracks and it opened and closed nicely.
What can folks tell me about the Prentiss Bulldog vises? I'm ready to learn. I can't wait to pick it up and get started cleaning it up. The jaws are 3-1/2".
It looks pretty rough from some angles. I hope you guys will be honest about the prospects of rehabilitating this vise? I suppose if it isn't worth fixing it'll make an interesting door stop. So far I'm out $25.
The first two pics are from the CL ad. Third pic was the best of the ones from my BIL.
Thanks!
Mike
Mike I am no vise historian but this is the little that I know about Prentiss.
Your Bull Dog 513/523 weighs 28 lb, has jaw width of 3 1/2 and opens 5".
The company was started by Mason Prentiss around 1868. The Bull Dog series might have first been manufactured starting around 1904. Prentiss as an independent company was in business until late 1940s (~1948) and then was acquired by Charles Parker. And Parker (and hence Prentiss) was then in turn acquired by Union Manufacturing in 1957.
I am sure there are other members here that have a lot better and more accurate info.
Came across a Colombian 504 sorry the pic isnt very clear.

Well, it looks to be in good shape other than the jaws. The replacement jaws will probably cost you almost what the entire vise will be worth when it's restored, but afterwards it will be a nice vise that you'll have rescued and can put to good use...

Contact esteemed vise guru and resident GJ vise jaw machinist, Kevin ScottThat's good to know Gerard. Any idea what kind of money I'm looking at for replacement jaws?
I'll have to decide whether this is a keeper or if I just pass it on.

I don't know of anyone who sells Prentiss jaws other than KMScott who is well known on this forum. I don't see your particular model listed but there is a 3 1/2" Prentiss jaw that might fit. Those are listed at $70 which in my opinion isn't a bad investment if the vise checks out as solid and will be put to good use. I think you'll just have to take some measurements and inquire.

I found this Columbian 504 1/2 a few months ago, I can't find a stamp like that anywhere on it...^ Every Columbian I've seen is stamped like that, here is mine.

Posted this over in the Yard sale thread but thought I would share with you.
Came across a Colombian 504 that has not been beat on and has clean jaws, just a little surface rust. I guess I have not seen a model number stamped like that before, sorry the pic isnt very clear.

1/2" jaw width, and a few more pounds...
Drivesitfar and gman007On Prentiss and needing model or jaw width
Mlutra
Not knowing the jaw width it might in principle be any of the models listed in the photo below (Prentiss with swivel base and swivel jaw). Now based on the only two provided dimensions namely the length of draw bar and length of the static jaw housing, the usable opening might be 5-6". So based just on this fact a shorter list of candidates might be
model 19 1/2 with 4" jaws and opening 5 1/4"
model 20 with 4 1/2 " jaws and opening 6"
model 504 with 4" jaws and opening 5"
Model 505 with 4 1/2" and opening 6" .
But even though it is hard to tell from the photo it seems the jaws might be none replaceable. If so it might even be a model 47 with 4 1/4" jaws and opening 5 1/4".
Again these are best guesses based on only the length measurement. And as Drives said a model number or jaw width will go a long way to provide a more accurate information.
They jaw width is 4 inchs for sure.Drivesitfar and gman007
Thanks for your Quick reply. I started to clean and take apart it.
Rusty, Is that the one with the Star of David on it? Kind of bizarre on a Japanese vise! Almost every time I see one, my first inclination is to think it is an Israeli vise. The one in this photo has the star on the static housing but I could swear I have seen a bigger star on the dynamic jaw as well but can not find a photo of it.
Edit
Found another photo but even though the star is bigger, it is still on the static housing , so my memory was half correct![]()
I JUST picked up this same vise last night. I have been racking my brain trying to figure out who makes it. It's a 90lb BEAST!
So, who does make it?
Sparty At least for me the photo is not showing up. To attach a photo use the Advanced button first and then you will see an icon of a paper clip on the top tool bar. Click on the icon and then use the browse button to find your photo and then use the upload button and make sure that it says it has uploaded it before closing the upload window.
Meanwhile, if the star of David has an N in the center or there are numbers such as No 150 on the vise, the vise was made in Japan! Some think it might be a copy of a Morgan and as we know Asian companies have never been shy about copying!
I know that. I was just curious as I had never seen this logo before and this was the first place I saw that had a similar vise. I'm just happy to have a monster vise sitting next to my anvil.
If you turn over the vise and look at the bottom of the swivel base, it should say Made in Japan
It does.
I do not want to be a party popper and dampen your enthusiasm but check the area where the slide meets the dynamic jaw and make sure there are no weld or brazing done there (from the photo it seems some work might have been done there). If there is, you might want to be gentle with this vise as that kind of fixes will generally not handle a lot of pressure.
Are you planning to do any kind of fix for the jaw inserts?

There is a Japanese, Star of David Vise on page 360, post 7181.---Another one on page 606, post 12109.---And another one on page 1154, post 23066.---All have the star on the static housing.
Maybe the CEO of a Japanese foundry was enamored with the Jewish religion or actually converted to Judaism or had a Jewish partner, or none of the above.![]()
That's awesome! Thanks for that. I cant wait to take it apart, clean it up a bit and mount it. It actually weighs more than my anvil. Anvil is 60lbs (about 90 with chain wrapped) and the anvil is 90lbs.

Sparty While 90 lbs might appear to be a monster to most people outside this forum, to the many of the vise nuts here, it might not be as impressive. Keep in mind US made vises are in general very hefty. Many of the 5" USA made vise with swivel base weigh more than 100 lbs and some like Parker 825 which weighs 130 lb. And that is just a start. Many members here have 6" US vises and those weigh 150 lb to 200 lb. Then again a number of members own larger vises say 8" US vises that weight 250-300 lb.

Either way it seems like a great idea!
It is not only a great idea but also the stand is absolutely gorgeous

I spotted this just today. It looks like a drill press base. Is that just an unreasonable price? $750 seems very high. Either way it seems like a great idea!
