An unusual vise patented in 1915, and built by North Brothers of Philadelphia who appear to have been in business from at least 1875 till the mid 1950s, though they were bought by Stanley in 1946.
They manufactured hand tools and small appliances and are best known for their line of Yankee ratcheting screwdrivers. Previous post here.
