I certainly would think, given that it's a Bechstein, it would be worth getting an opinion. You may have to pay for an appraisal. We had one on an upright a few years ago, and it cost about thirty five pounds. In the event, it turned out that the soundboard was cracked and it wouldn't have been worth the expense to have it restored, so we disposed of it and bought another one, which, to date seems to be in good fettle despite my less than tender musical ministrations! I've thought several times of replacing it with an electronic one, but to my ear, they just don't have the same resonance as a strung piano. Having said that, they aren't subject to the fluctuations in temperature that seem to send strung pianos out of tune if you aren't careful where you site them. Tuning is a problem these days as there seem to be very few piano tuners about. I would be interested to know how you get on.
