Unique piece of history! I would like to have it to use as it looks industrial quality! Maybe I can shed some light on the mystery.
Where I work all the equipment has a company inventory tag. Of course these tags are plastic and have bar codes but they use the tag to track maintenance, tell like machines apart and of course for inventory for the bean counters.
I would say this drill press was likely used by the Verity company in their producion of plows or whatever else they manufactured. Maybe even in the maintenance shop. When Massey Harris acquired Verity they probably got the entire business buildings, equipment, inventory and all. Sometime after becoming Massey Ferguson LTD it was inventoried as belonging to Massey Ferguson LTD at the Verity Works in Brantford Ontario. The V-8812 would have been it's ID or inventory number. The V likely stood for Verity.
I don't know where it was for sale from but Massey could have shipped it from Brantford to Batavia, Detroit, Racine, Des Moines or any other Massey plant as machines are always being moved from plant to plant for different reasons. Eventually it was probably sold when they closed a plant or when it became to worn or outdated for their needs.
Still it would be an exciting one-of-a-kind addition to anyones collection.
Upon further review - It also could have been purchased new by Massey and placed in the Verity plant. It doesn't really look old enough to have been owned by Verity.
