Actually,the George Way days.Those "turret" lugs were designed in the mid 50's by George Way,and used on his drums,till Camco took iniated a hostile take over of George Way drums,with va 51 % stock but out.
Till the early 60's ,Camco was a hardware manufacturer ONLY,and only after taking over George Way,and his patents,did Camco become a drum company.
But I digress.I too am not overly fond of those lugs,but I do love the sound of vintage Camco drums.Their shells were made by Jasper and later on by Keller.Extra care in the bearing edges is what gave Camco drums their characteristic warm sound.
Camco was also the only drum company, that would mount Rogers hardware at the factory,on their drums if a customer wanted it.
Some Camco afficinatos dispute this,but it's true.Rogers hardware was at the time ,considered the state of the art.
