Thanks all, that is a good reminder that she's 44 years old and deserves to show signs of her age. The checking and playing marks on either side of the strings were more or less what I expected, but the deeper and shallower dings below the bridge had bothered me. But you're right, if there aren't cracks and structural problems, the surface lacquer is just the surface and I should look beyond that.
Dear Es335, your suggestion of writing to Dieter Hopf to ask about the comparison with more recent models is a very good one! Thank you... I had not even thought to ask him, but will do so.
Dear Andreas777, if I decide to buy it, I would not ship it to Singapore, but only send to my Munich office. I will pick it up when I go again in October and hand-carry it back to Singapore. Or rather, I will try to arrange with the airline to allow me to hand-carry it back (since I will be in business class), assuming Munich airport lets me through with such a big piece of hand-luggage. Would you (or anyone else in Germany) know how strictly the Munich airport staff enforce the "hand-carry luggage must not exceed the specific dimensions" rules?
