We actually have at school Iskra's analog multimeter, it's similar design as this one, it has the same rotary switches, except, well its analog needle. I'll take a picture, but I'm not sure I can open it up without that special head screwdriver. I'll try to find an old flathead and grind away the middle of it.
And yeah, Iskra (translation is Spark) is now divided in bunch of smaller divisions and isn't the giant that it just to be. It must have been quite of sight using them and other famous company "products" around Yugoslavia. Well I can't really call those things products, everything from cars to electronics was made in Yugoslavia, and the industry was considered a national pride. Cars were national symbols, and the products of electrical and electronic companies were also considered similarly.
Honorable mentions include Sever, they mostly made electromotors and they still exist today, owned by Austrians (not Australians
), and EI Niš (pronounced Nish), they were also prominent electronics company, and they still exist today, one of the few remaining companies that still make vacuum tubes.
I'm one of those post war, younger generations, so I can't remember the life in Yugoslavia, but I've heard a lot of stories of people missing the old times.
There are still a lot of remains here of the things these factories produced, we used the other day an Iskra's relay timer, I've opened it up to see what's inside, and of course there was a 555 timer.
Thanks for the video Dave!
