Early Electronic Television
Fumeo
This set was made in Italy about 1930. It is designed to work with the 30 line Baird system, and the 30 line German system by rotating the viewing screen and the neon lamp. The set is stamped "Londro" and "Berlino" to indicate the two systems. The Baird standard was vertical scanning, with a 3:7 aspect ratio, while the German standard was horizontal scanning, with a 1:1 aspect ratio. The disk has two sets of holes.
