He says it's bronze.
So is this some rare duck or what's the story ?
It is supposed to have an original all bronze dynamic jaw.
Any thoughts from the vise historians ?

Hi, Shawn,
As others have said, the first thing to suspect is bronze paint.......that said, if a magnet doesn't 'stick', and that movable jaw really is a bronze casting, there could be a plausible good reason.
That style is meant to be a woodworkers' vise, of course, and so would likely be used in a pattern shop. If the original jaw was broken, the obvious repair, to a patternmaker, would be to glue the broken parts back together, make up a core-box for the core, and cast a replacement jaw from one of the high-strength bronzes, using the temporarily repaired past as a pattern, after building up its dimensions for shrink with glued-on leather or some such improvisation. Such a replacement part would be quite adequate for woodworking use, I should think.
(complete cast bronze Emmert pattern vises are rare, to be sure, but they are occasionally found, as the workers at a non-ferrous foundry could, and did, simply dissect an original Emmert, plug the machined holes, and use the Emmert parts as patterns for new bronze castings.)

Carla: i know Americans in general were handier concerning industrial type things in your day, but since vises were fairly cheap wouldn't it have been easier to just buy a new vise? or was it like some of us that like to fix something to make it work and say DAMN TO THE COSTS and time to do it?
or maybe shipping costs or being in an area that wouldn't even ship something to you might have been cause for the creative minds of some to just make a new tool by using the old one to make their molds?
The scenario of any shop making a pattern and casting their own dynamic jaw is highly improbable. Aside from the pattern, one would also have to make a core to fit the void inside the slide, so you need both a pattern and a core box. An engineer would then have to draw up plans for a sprue, gating, runners, and risers. I'm not saying it can't be done, just that it would be cost prohibitive. One could buy dozens of new vises for less than the cost of creating one dynamic jaw.
If the dynamic is bronze, the most likely reason is that it was salvaged from an all-bronze vise.

Hi, DIF,
Its true enough that equipment such as vises may be found relatively cheaply today, relative to the generality of pay scales, these days, but the situation was quite different, years ago, in the 'hard times', when $ was tight, and later, during the war, when you had to have a pretty good priority level to buy even something as basic as a vise (other than the cheap 'homeowner' types).
Have a look through a few 1920's through '40's 'Popular Mechanics' magazines, and note all the articles about 'How I made this nifty (drill press, grinder, table saw, etc.) from discarded car parts and a salvaged washing machine motor'. A lot of this class of improvised equipment might look 'hokey' to us, today, and might not have worked all that well, but the builders were ever so proud of their 'American ingenuity', and the 'get it done' tradition.
In those days, a broken vise would be repaired, rather than scrapped, if any reasonable sort of repair could be improvised with available equipment and materials. Even today, we often find old vises which were broken, and brazed back together, sometimes with improvisational steel strap re-enforcement added.
You may see a good modern example of this 'American ingenuity' on the internet 'Youtube' video programme, with a search on 'Tom Lipton' or 'ox-tool', and 'baby bullet'.
Tom is a machine shop owner, and a highly skilled toolmaker. For his own amusement, he made up an exquisitely detailed copy of a small Wilton vise 'from scratch', i. e., suitable pieces of steel.......literally a 'work of art'.

Allfast, I apologize--I saw the second post about it's being so far away but didn't connect it to you--the original poster.
Here's the CL ad. Looking at the rest of the pictures I can see it just might be bronze.
