They are vintage Pioneer.
Their TAD division still makes them.
The technique they use to make them as light and stiff as possible is quite remarkable. Because Beryllium ribbon is almost un-workable and can’t be soldered to, they make a copper ribbon first with the final pattern embossed on it.
Then they evaporate the Beryllium onto the copper. After masking off the ends of the copper they eat the middle away with acid leaving the Beryllium ribbon and two copper ends which can be soldered to.
