Kal-Equip Co. maker of high quality automobile tuning equipment from 1955 to 1979 in Otsego, Michigan

 

And other companies licensed the equipment and sold it under their own brands, like Firestone, who I've previously posted, sold tools made by Proto etc

I missed out on winning this at auction/estate sale. Damn, it would have been a fantastic piece of garage art! The guy who won it at auction, got it for 70 bucks

Kal-Equip was 1st used as a trademark in 1955, and they filed for the trademark in 1958  

Tunemaster was first used in 1960  https://trademarks.justia.com/720/62/kal-equip-72062399.html 

Some equipment was labeled Kal Tunemaster, and some was BK Tunemaster, which I'll guess is Bal Kamp

similar to the Sun Electronic Engine Performance Tester/ Master Motor Tester / Tune-Up Tester, might have been bought by NAPA / Balkamp. The trademark was cancelled in 1988

It looks like there was an attempt to pivot, and work under the trademark Peerless, and then the company was sold to Actron who sold through Sears.
