@Tonyanton26...With respect to the value of the vise, the historical value is invaluable. It's the only 1890's complete Hollands no. 115 vise in original condition that I'm aware of. It deserves to be in a museum or at least a tool collectors collection.
While Hollands Mfg. Co. vises were sold into the 1960's, your vise is from the era of the original founders.
"Caleb Hollands", President and a native of Sussex County, England.
"Edwin S. Rockefellar", Vice President and General Manager, born in Mechanicsburg, PA,
"William McWhorter", Secretary and born in Cincinnatus, Cortland County, New York and is of Scotch and English ancestry.
"Robert B. Hough". Superintendent and born in Brockville, Ontario, Canada.
These gentlemen all had previous experience with each other by means of their previous employer, the "Seldon & Griswold Mfg. Co., famous makers of quality cast iron products.
The following illustration shows an early Hollands Mfg. Co. plant. Notice that there are no cars or trucks, just horse & carriage and trains.
The next illustration shows all of their original vises, including your vise.
While I'm sure you're interested in the monetary value of the vise, I think you'd get your best value in a trade with a local tool collector. With that said, I really hope you consider just keeping it and appreciate it for what it represents historically as an early American Tool.
