1936 TRIMO SAW VISE SET
I don't quite know what to make of this but here it is.

"Special for the dairy trade"?

That's an interesting vintage advertisement for a vise for very niche, specialized application - thanks for showing it. This 1936 ad would have been right about the time when dairy farms were modernizing from milking cows by hand or using in-situ milking machines over to the concept of a "dairy parlor". This is a centralized location in the barn where multiple cows are milked at the same time by machines, and all the milk flows automatically from cow directly to a refrigerated collection tank via a multi-branched piping collection system, which has to be all food-grade and hygienic-rated, with no crevices that would prevent proper cleaning and sterilization. Not sure of all the details, but I think the burred edge from a typical tubing cutter didn't work with the type of fittings available in 1936, hence the special vise to ensure that the farmer or installer could make a perfect square cut when putting the piping system together.

Bonus comment, our dairy (and brewery) product piping was often Schedule 5, so very thin, and cutting with a hacksaw was possible.
