Pinnacle were a re-seller not a manufacturing company. They purchased valves from various places like Italy, Russia, Japan even some military surplus bulk stock.
Their main criterion was to get them at lowest cost, even un-boxed if necessary, then put their own brand name 'Pinnacle' on them. They then put them into Pinnacle boxes and offered them for sale at a lower price than a Mullard or Brimar etc.
Another company called Z & I Aero did similar with the brand name of Zaerix.
Another re-seller was called De Banks who added a twist. They supplied you with fully stocked valve cabinets for your workshop. A salesman would visit once a month to replace valves that had been used and you paid for the replacements. It is possible that Pinnacle had a similar arrangement with radio/TV repair shops and it was rumoured that De Banks were in fact Pinnacle operating under another name.
