Emco 13. 3" jaws on this Clamp-on. Missing the clamp.
Kevin,Atlas 2-1/2 I-beam Clamp-on vise. 2-1/2" jaws.
American Scale No 9. 3" jaws.
Ridgid 35 FSPN. 3-1/2" jaws on this Columbian made Combination vise.

Those early Wiltons used a 1/2” carriage bolt with a 1/2:13 Acorn nut. They put the lockdown holes too close to the side to accept a swivel handle lock down. The #3 on the spreadsheet was done by me but I made a custom lockdown where the handle buried in the swivel body so the handle would not touch the vise body.Mr. Scott can you direct me where to go for a 4-46 Wilton 3” bullet jaw clamp replacement.
Please excuse my lack of information. I am looking to replace a jaw piece that is missing. This model is a direct mount -no swivel option.
Mr.Scott, is there a variant with out the “B” on these? I recently found one and I was curious. I did a search of GJ and couldn’t find anything.Oswego 24-1/2. 4-1/2" jaws.
I made the assumption that the dynamic showing 24-1/2 A and the Static showed 24-1/2 B was casting ID numbers. It's always been a question for me should I list it as a B or A after the model number.Mr.Scott, is there a variant with out the “B” on these? I recently found one and I was curious.

Thanks!
Interesting. I didn’t even realize mine had that cast into it! Thanks!I made the assumption that the dynamic showing 24-1/2 A and the Static showed 24-1/2 B was casting ID numbers. It's always been a question for me should I list it as a B or A after the model number.

Impressive! But what do the code words mean??!?! I’ve never seen that either.No variants on the "Oswego / Sawyer Tool" machinists vises that I'm aware of. All of those particular vises, stationary or swivel base, had the casting "A" (dynamic-jaw) and "B" (static-jaw), as suspected by @KMScott .

Here's the Oswego Tool Co. catalog scans with the model nos. for the machinist vises. I believe they used the same model numbers throughout the life-cycle of those vises.

The "Oswego Tool Co." has always been one of my favorite reads, since collecting vise data. The rich history of that region dates back much farther than I'm used running across in my vise searches. I'll leave you with what I consider to be the most significant historical feature for the "Town of Oswego", the Oswego River / Canal leading to Lake Ontario and all of her borders.

Lots of different old hardware catalogs had code words like that, I believe they were considered Telex code words so that you could send a four or five letter word instead of a long string description to make sure you got the right product.The "code word" was a unique word affiliated with each specific vise model / size and used in the ordering process. While this was not common practice for most of the vise manufacturers, it was used by a few of them, including an early Wilton Tool Co.
could be classified somewhere between 'toy' and 'cheap tool'.
Yep starting in the late 50's fast framing was key, but this was made in the prewar years, think craftsman or storybook houses, the kind that scream workmanship... that framing is not factory line...For someone who only was framing one or two structures, a vise like the Porto-Vise could be very helpful.
Most professional vise manufacturers who made woodworking vises used to offer those, and many still do.It seems like this could be classified somewhere between 'toy' and 'cheap tool'. It probably had its uses and, for someone, it may have been just the thing needed.

Rock Island 603. 3" jaws that opens to 3-1/2" and weights 18 lbs.
Went back and checked and you are right. Ended being 12lbs Not 18. Good catch. You got one? Thanks for catching it.Wow, I'm a bit shocked at the weight on that homeowners vise; RI or no...
