In a company that maintained some kind of office for more than a century, Vulcan used many office technology that would be considered “legacy” today. In this case we’ll consider one: the Dymo Embossing Labeller, in this case a Mark VI (M-6.)
It’s shown in the context of the Fluid Mechanics Laboratory at UTC, where it’s still used. That laboratory is not so from from Vulcan’s Chattanooga Factory.
The machine used actually came (I think) from Vulcan, which used it for the extensive collection of notebooks that it maintained, along with other office items. It remained the normal way of labelling things until the electronic labellers came into use in the 1990’s.
