I don´t think that I´ve ever seen this one before

Sorry for the extreme lateness of the response - my presence on s2g is a bit hit & miss these days...
It's a 3D9 - one of the first generation & the only 3pc Hitachi 3D. The tape deck is the best ever fitted to any 3D, servo assisted with a nice, big flywheel & it has Dolby too. Sound-wise it's very "grown-up", but there are other first gen. 3Ds with a deeper thump to the bass (3D7, 3D8, etc.). Build quality is a bit plasticky at the rear, but it's fine at the front.
If it's fully working & that price is in Swedish Kronor, then I think it's a good price (around £25).
