As reported in the Garage Sale thread, 3bay found a neat vise a couple days ago – a Desmond Stephan with a Defense Plant Corporation data plate and copper jaw covers.

I told him I would post some elaborating info over here. This is it…
3bay,
This February 1945 War Department TM –
- has two great photos of a Desmond Stephan double lock down swivel base bench vise.
Fortunately, it has been scanned by the University of North Texas and is on-line. Link to first Desmond Stephan photo here:

What’s interesting about the jaw caps on yours is their composition. Eventually the broad restrictions on copper and brass, being preserved for munitions, caught up to jaw caps. As I first reported in a summary of Limitation Order Schedule VI (Vises) here (
http://www.garagejournal.com/forum/showpost.php?p=6485654&postcount=631) on the ‘Wilton Dating’ thread, after January 1944, jaw caps could only be made of lead or lead-based alloy. Here is the excerpt itself:
That dates those jaw caps, the date of their fastening to that vise, and most likely the vise to earlier in the war.
As I reported in a summary here (
http://www.garagejournal.com/forum/showpost.php?p=6509492&postcount=655), also in the ‘Wilton Dating’ thread, Desmond Stephan was supplying vises ($297,000 worth) to the US Army Quartermaster Corps and Navy from 1943 to 1945. Here is their entire record:
Given the data plate on your vise, it sure looks like Desmond Stephan was also making vises for the Defense Plant Corporation. As you already know, the DPC built entire standalone production plants, converted other existing facilities into defense plants, or bought equipment for the purpose of expanding the capacity of an existing plant. The DPC also purchased machine tools and hand tools and allocated them to private industry. According to the WPB Major War Supply Contracts books I have, they also had massive contracts ($13.225M) with the Air Corps, the Corps of Engineers, the Navy and others. None of those contracts were for vises, exclusively, but I suspect they were included in one of the ‘HAND TOOLS’ or perhaps even one of the ‘MACHINE TOOLS’ contracts on this list.
It’s uncertain to me whether the items they were supplying to the services under the contracts above were going directly to those services or to plants those services were using for production. Either way, your vise looks like an early wartime vise made by Desmond Stephan for the DPC for one of their plants or for delivery to one of the services plants.
