HP may have indeed used Weinschel attenuators, back in the days when Bruno Weinschel was still alive.? Weinschel is a shell of what it used to be, not the quality brand it was, unfortunately.

Many of the well respected names are now only shadows of their once greatness or no longer exist in name or physical state - once the suits get a hold then the engineering led way goes out the window in favour of the fast buck.

HP, Weinschel, Marconi, Racal, Plessey etc. etc.

Best to remember their greatness and the legacy they leave in the superb products of past times.
