That v slot is a great idea.  Thanks for sharing. 

Timberframer: thanks for sharing those photos.  

The anvil on the left seems to have the remains of a logo; right where the upper swage indent is located.  

TRL,

I think your plan is straight forward and practical - it reminds me of the columbian vise boxes.  If unsuccessful, replacing the original screw with an acme and nut, similar to shown in some videos online, would likely be next course of action, although more work.  

For me, the process is often as personally rewarding as the results.

If you go forward with the repair, post pictures!

Very interesting; thanks for sharing Julian.

Caotropheus, in the below link, the original poster indicated that he is a professionally trained German smith.  Perhaps you could try and send him a message?  Those vises are quite interesting I'd say buy one just in case!

Mr. Pete has a youtube video, wilton vs columbian.  The vise in your picture looks very similar to the columbian in his video.

Columbian

Nice Yt12....  For those not afflicted with the vise vice, this is a Charles Parker.

Looks good and functional!

Seagiant.  That Starrett is a fantastic vise... I'd happily trade a few of mine for that one.

Frosty you got it.  I coudn't recall the rules for other sites so I didnt want to put too much of a url.  

If someone is ever in need of identifying an unknown vise, some dedicated soul created a searchable spreadsheet that can be found at the same site.  Over 3k vises.  

Rhett, vintage vises has a nice collection of data for all things bench vise.  They have records of 3 columbians in a similar pattern as yours, weighing between 160 -180, depending on model.  

Picked this up today on a bit of a lark.  It was absolutely covered in very old dirt.  Cleaned it off and it indicates a 1 - 0 - 10 hundredweight at approx. 121 on my scale.  It is in surprisingly good shape for what info I was given - abandoned in an old barn.  As the title indicates, I'd like help with an ID.  This will be used by me (mostly my children, actually) and not resold.

The (seemingly) unique thing is the weight is on the opposite side of the maker stamp.  I can only make out but so much of the name, probably "warranty" and above that "W", maybe a space, two unintelligible letters, then what appears as "CYD"... maybe "OYD" and W Floyd? Anyway, I thought perhaps one of you may know of makers that put the hundredweight on the other side of the body.  

I attempted to lift better prints with chalk and pencil and paper etching - no success.  

9 3/4" tall, 21" long, 4" wide at face. Good rebound.  All in all nicer than I expected pre-purchase and I'm interested in seeing how it compares to my heavier PW.

Thanks for the swags gentlemen; they're more educated than mine and I appreciate them.

And thanks Thomas, I figured I could shim it up but your way sounds good.

This came with my anvil when purchased and has since been "rediscovered" by me in my shop after some time.  The fellow I bought my anvil from didnt know anything about it other than it came with the anvil when he purchased that 40 years ago in PA Dutch country.   The body of the tool is rather large for the shank, which itself is too small for my anvil hardy.  Is it just an over built cutoff?  The angle seems wide for that.  The apex is worn down but I have no idea if it was sharp at some point or not. The only making is an O or 0.  Appreciate any help identifying it before I repurpose it.
