The colours don't say Guys and Dolls but they almost do. Even / especially in the Eighties a Guy might have got some strange looks getting a Pink one out of his bag. Very smart looking unit though. Only looking closer did I notice the patterns on each one which are more subtle on the Pink and Blue. I have a 1980s Quilt cover in almost the same colour and pattern as the Red One. Diagonal lines like that were all the fashion back then.
i allways loved the kt-as10 for it's design and one will allways be in my vitrine of "most beloved units", but they're a pain in the bud to use with a cassette
