Joseph L Ware 5" model. 5 inch jaws that opens to 7-1/4 and weights an estimated 125lbs with the swivel plates missing. Vise as it sits weights 105lbs.
Super rare Athol no.20 Simpson swivel-jaw vise, complete with original handle. This vise is from the 1890's and possibly the 1880's. Unlike some of the other Athol swivel-jaw vises, this one has non-threaded pins.
jaw width......3-1/2"
jaw opening...3-3/8"
weight..........30-1/2 lbs.
I'm very pleased with this find and at this point I'd say 2020 was a pretty good year for my vise collection.

Wow that one is amazing! The swivel jaw on it looks like a Lewis. Nice grab!!
Dave, interesting that you mention it looks like a Lewis, which was later acquired by Prentiss.
FJ, I was under the impression that Simpson (as well Blake & Shepard) was acquired by Prentiss? If you are sure it was Athol, then a correction would need to be made on the spreadsheet for Simpson, which has Prentiss in parentheses.

yarrum, I see a lot of work in the building of that outfit.---Friction concept on the telescoping as well as the rotating.---Very good.---A lot of factory rotators use that same technique....How long did it take you to drill all those holes in that plate?![]()
yarrum...The photos are small, but from what I can see, that double-swivel vise stand looks heavy-duty and very practical.
I like the idea of a traditional vise on double-swivel stand.
I just got this littlestown no 1 in the mail today. Didn’t see it on the spreadsheet. But I’m not entirely sure I’m looking at the most up to date version of it. If you want more detailed info let me know and I’ll grab it for you
Greetings and salutations...Why do you think that the "Simpson patent vise" was acquired by Prentiss? What are you using as a reference for that information?
)Sambre & Meuse, from Belgium. 8" offset jaws that only weights 77lbs.
Nice Dave.---Rare.![]()
davethorik...Very nice find! It's another "unicorn vise" for you. You've been on a tear for over a year now.
I need to borrow some of your vise energy and find something special for my collection.
Thanks Nexoidian, jaw width and weight if possible, I know it's pretty light.

Hello everyone and thanks for allowing me to post my first reply.
A good friend shared a posting he found on craigslist. It was for a large vice. I decided to go take a peek at it. The seller had the vise fully extended so the threads would no longer open or close the jaws. I decided to take a gamble and buy it. Then to my amazement I discovered that it is made by a company called Union Backus.
It's very old from some quick research on Google. I can't find another example if one with 8" jaws. Please share a reply if you know of one and or collect this brand.
Over 160lbs and 25" long. No repairs or welds. She's a monster that's for sure.
To my knowledge Backus never produced any vises larger than 8".
Thanks for looking !!

Fierljeppen, sorry it has been a while since I checked in.
I can't recall exactly...back when I first started with the spreadsheet, seems I saw some brochures that had Simpson vises under the Prentiss brand. Again, it has been a few years now that I have not done research and checked brochures, so not sure. I just remember that on the spreadsheet I had put Simpson as Prentiss, because of something I came across at the time.
Of course I defer to your info as the brochure is right there! (and my mind does not always recall well)

This looks to be the one on EvilPrey listed for $1700.00.
The jaws on the EvilPrey one appear to have been replaced at some point. Have several Backus patent patent vises made by Millers Falls. The older ones have "cast in" jaws and the newer ones have replaceable jaws. None of the replaceable jaw vises have the jaws extending below the jaw pads.
My smallest have 2" jaws, largest 6" jaws.
