What you see is what you get; there may be a piece missing in this set ? 15 pieces total is what you will recieve; plus the original red tool box marked MADE IN USA !!!! Proto was founded in 1907 by Alphonso Plomb, Jacob Weninger, and Charles Williams as the Plomb Tool Company, a small blacksmith shop making chisels in Los Angeles. In 1933, Plomb released what is commonly credited as the first combination wrench.[1] Plomb acquired a number of companies during the 1940s, including Cragin Tool of Chicago, Illinois in 1940, P&C Tool of Oregon in 1941, Penens Tool of Cleveland, Ohio in 1942, and J.P. Danielson of Jamestown, New York in 1947.[2] Penens Tool would produce tools under the Fleet and Challenger brand names after its acquisition.[3] In 1946, Plomb was sued by another tool manufacturer—Fayette R. Plumb, Inc., now a brand of Cooper Hand Tools[4]—for trademark infringement.[5] The company began manufacturing its tools with the Proto name, a portmanteau of "professional" and "tools," in 1948. In 1957, the company began operating as Pendleton Tool Industries.[6] In 1964, Proto was acquired by Ingersoll Rand, and in 1984, it was acquired by Stanley and became Stanley Proto Industrial Tools. Third Generation: S-K Logo with Model Numbers, From 1944 The next change to the socket series was a minor cosmetic update, the replacement of the "S-K Chrome" logo with a simple "S-K". The sizes and model numbers continued to be marked as well. Third Generation 1/2-Drive Knurled-Base Sockets, Marked "S-K" with Model Numbers, From 1944. The last picture we have added into the listing comes from a alloy museum, showing a partial set of third generation SK sockets. This picture is for identification, of course those sockets are not included in the auction, however they are the same as the sockets in the auction. These sockets, with the model numbers (mostly) visible on the larger sockets. The bottom row sizes are, left to right, 9/16, 19/32, 5/8, 11/16, 25/32, 13/16, and 7/8, and the top row sizes are 15/16, 31/32, 1", 1-1/16, and 1-1/8. Note that the above sockets include three of the less common sizes, 19/32, 25/32, and 31/32; a fourth size, 21/32, may have been available at this time as well. According to the S-K catalogs, the availability of certain sizes changed over the years. For example, the 1939 catalog offered all of the 19/32, 21/32, 25/32, and 31/32 sizes, but a 1957 catalog shows that the 21/32 and 31/32 sizes had been discontinued by then. The approximate date for the change to the S-K logo can be inferred from the existence of certain unplated sockets bearing the new logo. Fig. 4 shows several knurled-base sockets marked with the new "S-K" logo, but with a plain steel finish instead of the expected polished chrome plating. Fig. 4. Knurled-Base Sockets With "S-K" Logo and Unplated Finish, ca. 1944-1945. Chrome finishes were known to have been discontinued during the 1944-1945 war years, due to government mandated rationing, so these unplated sockets were likely made during that time frame. This would place the transition to the S-K logo some time around 1944 or prior. We accept Paypal as a form of payment. If you need to pay another way please contact us before making your purchase.
