Telefunken-Karolus Matrix Display

We originally thought this was made by RCA, since the photos came from the Sarnoff library. Paul Lindemeyer identified it as made by Telefunken-Karolus. Below are clips from an Italian dossier on tv dated 1936.

Captions indicate the Telefunken-Karolus system. The left (first) pic is on the ETF page, in hi-res scan. Consider too: Would RCA have built a 100 line matrix display in the early '30s, when doubling their system resolution every year and a half - from 60 to 120 to 240 - and going all out to refine the Kinescope at each step of the way,
