I had the Panasonic too, and also wish I could still get one. Had to settle for the Panda (China) version, nowhere near as concisely engineered.
That photo shows 2 Pana characteristics, the single wide hinge lever and the flat covers. If the peller was offset (rather than orthogonal) that would just about cinch it. But I never saw a Hitachi live, may be closely related.
Actually, last time I looked you COULD still get a Pana TT if you were willing to pay shipping from........ wait for it......... Kuwait!
