tgordon, I believe the British vice were Wilton, but the new Wilton vices I've seen made in England, for sale here, did not have that quick device, I thought that strange. For instance, every Drill Press I ever used in Britian at work or home workshop type were all SELF FEEDING, The handle you use to make the drill contact the workpiece, on contacting by moving handle in the direction of the drill press it would lock in the automatic feed. For the home hand crank stand drill press, there was a horizontal flywheel at the top of the spindle and that would feed the spindle thus drill bit progessivly through the part being drilled. The quick acting industrial vises were very heavy duty, one would clamp a piece of steel and use a 14 or 20 llb. sledge hammer to bend it, so there was no reason to suspect their design. For hand tools America lead the World, real works of Art, a quality tool for any job imaginable, plus may could last for several Lifetimes, if you could see the tools that British Royal Air Force mechanics had to use to service the Rolls Royce Aircraft engines you sure wouldn't want to fly one. No wonder the engines were called Merlin, the name of an Ancient Welsh Wizard.
