Kent Moore wrench

Here's a nice water or fuel pump wrench, special tool J-4242. I can't find much info on the origins of Kent Moore, but for years they produced specialized service tools, equipment, and diagnostic instrumentation for the most of the major players in the American automotive industry, 

In early 1982, Sealed Power, a engine component manufacturer acquired the company in a cash and stock transaction valued at $70 million.  An important step in Sealed Power’s campaign to diversify its product line, the acquisition of Kent-Moore provided a new direction for Sealed Power’s relationship with the auto industry. Although Kent-Moore dealt directly with the same automakers that Sealed Power had supplied since its beginnings in 1911, the specialty tools that it produced relied on the introduction of new automotive models rather than on the volume of production. Each new car model requires a set of specialized tools with which dealers can service the vehicles, and the Kent-Moore division works directly with manufacturers before new vehicles are introduced. Kent-Moore also had significant overseas operations, including a partnership in Japan, that allowed Sealed Power to expand its foreign presence. Encyclopedia.com

In 2013 SPX was acquired by Bosch but I believe the tools are still being manufactured.
