@ Kevin!
Yes, you are right, Stromberg-Carlson made TVs in Australia (not only radios).
Stromberg-Carlson Australasia Pty. Ltd. was placed at 118-124 Bourke
Road, Alexandria, close to Sidney.
They started with a 17"/90° set in December 1956 (model: 517 Olympic/ table
set and Pembroke with long legs, aussis called them low boys).
In 1957 they offered a 17" (model 717) and a 21" (model 521 called Royal).
At the end of 1957 to the beginning 1958 they sold the models 817 (17")
and the 821 (21").
In the 60s they offered the 110° sets called: 4A-002, 4A-004, 4A-005/4A-005/1,
4A-091, 4A-092, 4A-311, 4A-312.
That was the news from a german "down-under-TV"-fan, who called 7 aussis
his own.
