This is a fully-articulated scale model of the Emmert patternmaker vise, constructed in what appears to be mahogany with bronze castings. The model is similar to the original Emmert "Turtleback" design with a few exceptions. Interestingly, the model is identical to drawings submitted by Joseph Emmert as part of his application to the US Patent Office on March 16, 1891. US PTO approved the application and issued Patent No. 457,710 on August 11, 1891. Per the patent document, a working model was not submitted to US PTO as indicated by "(No Model.)" on page 1.
Note: The front jaw of the scale model has two keyholes which match the patent application design; one keyhole is oriented up/down and the other is oriented left/right.
The Emmert Vises I've seen have two keyholes in the front jaw, but both are oriented left/right.

The scale model is missing three parts:
1) the "Cap Plate" shown as "V" in Figs 1 and 2; there are three screw holes in the front vise jaw where for attaching this part, but the cap plate and screws are missing.
2) "Casting B" shown as "B" in Figs 1, 2 and 3
3) "Sleeve/Flange" shown as "D" in Figs 1, 2 and 3
It looks like Casting B was made in wood on the model and broke off at some point. Casting B when connected to Sleeve/Flange D was the hinge which mounts the vise to a workbench.
Ironically while those pieces are long gone, the tilt/angle bracket that's frequently missing on actual Emmert vises is still connected.
This model has all features of a real Emmert vise. The jaw angles, the vise tilts up and down and the body spins 360 degrees. The bench dogs are made of wood.

The overall quality of construction, detail and materials used are consistent with patent models of that period. There's no evidence suggesting it was submitted to US PTO. It's possible it was built for that purpose and not submitted, or perhaps to as a proof-of-concept.
The other possibility is that it's a salesman sample. It seems unlikely since there's no Emmert label or markings of any kind, but perhaps that was on the missing "Cap Plate" cover.

The man I got it from intended to use it but never got around to mounting it on his workbench.
