I couldn't find any other ads on here, I thought there were a few? From 1983 Germany, two look like Pioneer, and the big one looks like a Sanyo, I kind of like them but super-rare around here.
I'm not getting any information on the TSR-602, it looks like it could be a nicely done boomer. The TSR-951 is also a nice looking box with rounded top and bottom. This page takes forever to load but there's some nice photos. http://audiopub.co.kr/2018/01/27/금성사-오디오-포터블-카세트-라디오들/
That TSR-700 is probably the rarest Goldstar. It's also one of the oddest-looking boxes. Very low-slung and wide, pretty cool. Not sure why it needs to be so deep, though.
@Mister X has often commented that he likes boxes with multiband tuners. Is twelve on the one with the four speakers arranged vertically enough for you ?
