Jeff357...Yeah, you nailed it. Your Bryant vise has Studebaker written all over it. Great find!
Studebaker Start Machine Firm
"Two names familiar to the automotive field have entered another branch of industry. J.M. Studebaker and his son, J.M. Studebaker, III, have formed the Studebaker Machine Co. to produce hydraulic vises, riveters and presses.
Both were until recently directors of the automotive corporation that bears their name. The new company will operate under an exclusive license with
Bryant Engineering Corp., Cicero, Ill., which owns the patents on the devices to be manufactured. Sales offices will be located in Chicago and executive offices in South Bend, Ind."
