The woofer: Unitra was the company name in the old days and it became later Tonsil so the woofer might be allready an original replacement.
No. Unitra didn't manufacture anything. It was just an association of several companies.

Tonsil existed as Tonsil before Unitra and now, after Unitra is gone. I have several 1950s Tonsil, pre-Unitra speakers.
The original woofers with textile surrounds disappeared in the early 1980s, later woofers had foam surrounds that would rot within 10 years.
The screw type terminal might be an export-only thing. The DIN sockets were replaced with push button type terminals circa 1980-81. I live in Poland and I know most of the stuff that was produced here. In fact, my father has a pair of ZG40C/8 speakers, just like the OP's but with a Polish language plate on the front and no screw type terminal.
