Probably around 1995 and either a TS100 (top line) or the next model down. Is there engraving on it possibly including the neck? Hard to tell if it has two oval pearls for the right hand, side F# and high F# - I see one for high F#. The neck for the top line has no brace. The white felt bumpers in the key guards is throwing me as I would expect green, although they could have been replaced.
