Lots of great advertising quotes on the ruler:

"The special fercrome steel will resist the fiercest heat of modern high speed motors and will continue to function perfectly!"
"A product of Jadson motor valve company"
" Jadson's valves stand the gaff"
"The life of your motor depends on your valves"
"That is why they hold more speedway records than all other makers combined"
"They will not warp or burn out under the most intense heat"
GAFF - Take severe criticism or other adversity in stride, as in If you can't stand the gaff, don't try running for office. [ Slang; late 1800s]
In 1937, Thompson Motor Products bought J.A. Drake and Sons (JADSON). The company made high-performance valves that were used in many racing engines of the day, including the Miller Offy (Offenhauser engines). Dale Drake (son of J.A. Drake) bought the Offy engine design with his partner Louis Meyer in 1946 and won the Indianapolis 500 twenty-seven times, more than any other engine design.
Thompson Products and Ramo-Wooldridge merged in October 1958 to form Thompson Ramo Wooldridge Inc.,unofficially known as "TRW".
In 1946 the name and engine designs were sold to Louis Meyer and Dale Drake. Meyer was bought out by Drake, his wife Eve and their son John in 1965. From then until Drake's son John sold the shop to Stewart Van Dyne, the Drake family designed and refined the engine until its final race days. It was under Meyer and Drake that the engine dominated the Indianapolis 500 and midget racing in the United States.
