You may have already found an answer or totaly forgoten about this, but better late than never. The deck in question is a TC-800. Verry desirable machine in mint condition from a design repect for a colector. I remember seeing it in my parents Hi-Fi shop when I was a kid. The TC-800 was designed by an Italian named Mario Bellini who also designed the super cool looking Olivetti adding machine on my fathers desk in the same shop,I don't know witch I would rather have now, the tape deck or the calculator. If my memory serves me well you can find both at MOMA.
