Leet Manufacturing Company // Leet, C. D.
Bridgeport, CT - Listed under Vise Manufacturers in the 1890 Railroad, Telegraph and Steamship Builders' Directory. We assume this is the same C. D. Leet who got his start manufacturing firearms cartridges. That enterprise was purchased by Winchester in about 1881. Mr. Leet had numerous patents beginning in the 1860s.
Here is an article from the Boston Mechanics Exhibition of 1884 about Mr. Leet's Vise.
