All of those Korean Brands were maligned pretty badly here, I'm surprised Hyundai lasted with the constant beatings it took but to be fair they'd start rusting as soon as they got wet.
Yes. LG = Lucky Goldstar Back then the Korean brands names carried no kudos at all. In a different thread were talking about UK brand Ferguson. I have a Ferguson clock radio bought new in the mid 1980s "Made in Korea". It wouldn't be surprising if it was actually made by LG or Samsung.
