Dear leg masters in need your help to identify my new Vise, it has 1911 and 60 on, I don't even know how to determine the size,here are some pics. Thank you in advance for the help

A measurement of the jaw length helps. Also, the weight of the vise would be good to know. But your vise is secured to a base. (concrete?).

It looks like a winner. you'll get good service from it.

SLAG.

I had a post vise encased in concrete just like that. I freed it with a sledgehammer and gave it to a friend. cant help much on info but free it and use it.

I have a 6" post vise from the same manufacturer. Mine has too many hammer marks to make out the logo, but it says 1902 in the same spot. Mine is marked 85 under the date and weighs 85 pounds. Yours is probably a 5" vise that weighs 60 pounds.  ...without the concrete.  I'm also interested if anyone knows anything about that company.

Thanks guys, so I'm understanding it would be best to break it out of the concrete? Again thanks for all the help

How are you planning to mount it?  Is it at the correct height for what you want to do with it?  Might be better to just set it in a hole where you want it and at the correct height.  That is if you plan to use it.

Also remember that a lot of stuff is stamped with the *seller's* mark and not the maker's mark

The jaw width is the size, 60 is probably the weight, the 1901 would be the year, and try a Google search of the stamping W&WH Co. That is above the date.

Upon further investigation, the logo is actually VW&WH Co. That means it was made by some other company, then distributed by the Van Wagoner & Williams Hardware Co.

Thank you to all who replied and gave input,especially you C-1 ToolSteel, for helping decipher who made that beast, I measured the jaws they are 5 inches, I broke it out of the concrete.

Looks like a Columbian.
