I found one for the Spreadsheet: A Bryant Engineering Corp. Cicero Illinois.
This is the same as the early Studebaker vises from what info I have found.
I do not know if this was before, or after the Studebaker vise.
This one has 4" wide jaws, 5" opening. No weight at this time. Unless I weigh the entire frame and pump assembly together.
That weight I can add later.
The hydraulics are in poor shape.. i've already made a new cylinder for the center pedal's pump. It has a cup shaped leather seal, and an internal compression return spring. The right and left pedal are for tightening and releasing respectively.
The piston for the actuation cylinder is very pitted. but it is just under 7/8" so i can turn a new piston for it..
I might be able to make it operate hydraulically relatively soon..
The rear support for the actuation cylinder is broken and repaired.. I'll fix it correctly and it will look much better.
I have all the pedals for the base.. I removed them to take an unobstructed photo of the base.
I have no idea what the 'F1' stands for. There is a 'V3' on the inside of the rear [dynamic] jaw tower.. And I have not clue
what it signifies.. If I find more info, I'll post it for the spreadsheet.
Pretty interesting production vise.. I'll properly repair the cylinder's rear mount. Jaw inserts smooth.

I removed the center and right side pedal to take the photo.
Kinda of a neat item..
