Sold for a about 16K. It cost =A399 in 1936. So with inflation the 16K=20
isn't so great!

Enthusiasts use 625 to 405 converters. A picture was shown on it at auction=

There are a few experiment 405 line NTSC variant TVs surviving from=20
1950s when BBC tested about every colour system before deciding on 626 PAL.

A 12" 1936 TV is about the same resolution as a 42" HDTV :-)
