I have a wilton with the J-C cast also did you find what it is?

Can anyone help date this vise? Is this one of the older versions not best suited for every day use/abuse?
Cooper, yes that is an early version. "Chicago" vs Shiller park, Acorn nuts for the swivel, indentation into the main body next to the acorn nuts, etc.
As someone else mentioned, the real method to date these is to check the date stamp on the key on the bottom of the moveable jaw. Let us know what the date is already! Lol
I'm not sure what you mean by the older vises not being suitable for every day use. Sounds like someone has sold you an old wive's tale. Yours is likely over 60 years old! Seems to have held up just fine.
If it's not "heavy duty" enough for you, please let me know when you have it boxed up and I'll provide my shipping address. Haha
Very nice vise!
I have a Wilton 150 OS, which is clearly a rebadged Dawn 150mm Offset vise from Australia....
In Email from Dawn a couple of years ago, the association was clearly less than happy.
I wanted to buy a second one from Dawn..... they had exactly zero interest in exporting to the US and had no trouble saying so.
At least one on ebay, see item eBay item number: 282318627891Drives, I may have to eat my words, but here is what was within an ebay ad about the same vise;
"“The Offset feature provides the facility for holding long vertical work with the full width of the jaws without obstruction from the main body of the vice.”
“The Super Grade Offset Vices are the jewel in the crown of vices produced by Dawn. They provide positive grip without springing and are ideal for heavy-duty applications. This world class vice which is unique to Dawn is simply the best vice a tradesman can own.”
(from the Dawn website)
This was made for Wilton in Australia.
Jaw opening = 7 ¾” Weight = 128 lbs.
(see information on box)
-----This is from an email from Dawn:-----
We ceased manufacture for Wilton in 2002 as I believe at that time their company was undergoing major restructuring and changes culminating in their ceasing this product line.

After looking over the photos in the ad I'm wondering if I only saw the sticker in the ad, which says "Made in Australia".
I picked up a "yard ornament" yesterday at a house I was working at. It was half buried in a flower bed. I offered $60 & the owner promptly accepted. 6" jaws. Rusty. All moving parts still move except for one of the swivel locks is froze.

Edit - Date stamped 5-79. After soaking in penetrating oil last night, I was able to free the stuck swivel lock. The vise appears to have been originally painted a funky shade of green.


I just picked up a old dirty Wilton from a old shop.
It had been sitting on the floor collecting dust and rust for years!!!
I decided to clean it a little last night, It's completely chrome (or nickel) plated!!! and it looks like it has never been used (like a display for conventions or something?)
Any idea what I have??
does anyone know when wilton started using ductile iron in their combo and machinist vises?
I believe I may have blown the warranty date theory or the production run startup/company inception slap out of the pool, because I have just opened up a 5" 1750 by way of hours of heat, pressure, and sweat... :
Dynamic Jaw: three distinct marks: 101018 / 7-40 / 6

I'm guessing it was painted which is weird with as little of use as it has. Did they paint them black in that era?
Wilton makes note of ductile iron (used in stressed areas) in their 60's catalog. I interpret it to mean it was not used until that version of their Machinist vises. This makes sense as Columbian started making ductile iron "unbreakable" vises around that era as well.
