Pics might help, but we have only ID'ed a few manufacturers. some by features common to the MFG, and some by the 3 digit model no. Prefix. The ones we are certain of are in the posts.
We've not ID'ed that one, but it seems to me one or more with the inverted "U" slide appeared in the vise thread, and was a likely candidate for the MFG.
Outlaw - thank you. Would the supplier have been Columbia, or ..?5183L is your vise; the catalog number may be similar to the Model No's, but never seem to match 100%

Awesome to see this thread is still active- thanks Outlaw for your work in this thread!! I just stumbled on this after trying to identify a vice I've had for over 20 years. It came from my grandpa and has been an absolute workhorse all my life. As best as I can tell, it appears to be a Craftsman 5242 based on the 1940 catalog page. However, either the "Craftsman" name casting was ground off, or it was never there. Did Dunlap make this same model and use a sticker perhaps? Jaws are 3.5" and it opens just over 4". It weighs in at 20 pounds.

It sure looks like that model. and I agree the markings appear to be ground off.
Dunlap was a Sears trade name just like Craftsman, so there was not "Dunlap" manufacturer. I have no clue who made these vises for Sears.
A long time searching in the Vices thread might surface it's twin with an OEM's markings.![]()
a member just got one like that, was asking about bolt sizes?A few more Craftsman vises for reference sake.
A Craftsman 506.51801 vise with 3.5" wide jaws. I always liked the look of this style vise. This one is in pretty nice shape.
