"made in Yugoslavia" - it would probably be made by Gorenje.
Gorenje fridges and washing machines were sold here in the 70s and 80s badged as Pacific, usually somewhere on the appliance there was a small badge that said "Pacific by Gorenje."
Later Email / Southcorp imported some Gorenje appliances with local brand names they owned such as Simpson and Frigidaire on them. The "Simpson" front loaders from Gorenje were pretty popular. This company was eventually bought out by Electrolux and I think the connection with Gorenje stopped around then???
Kleenmaid, an Australian company that mainly sold rebadged Speed Queen washing machines, also offered some Gorenje fridges and washing machines, again badged as Kleenmaid.
So it seems Gorenje have been happy to make appliances with many various badges on them, and my guess is that the little Hoover fridge is one of them.
