    How many among us have encountered a Steinway with 1) Absolutely no serial number anywhere to be found, or 2) Serial number ONLY printed on plate but no where else?

    Mostly just curious at this point. Thus far I have encountered one each of the above.

    Peter I have a B in a church - non-teflon - it's a mystery. It was a mystery before I started servicing it 12 years ago. The church knows. It's on a stage dolly so taking off a leg to find out of a number is hidden there may be the only solution if they were that curious. They would be calling my mover if that were to happen.

    Yes, when I get to see the current one in person (with # on plate only) I will do exactly that (drop the lyre). It is theoretically a 1959 model L. It does have the wrinkle finish style on the plate (1955-1959) so that checks out, and original plastic keytops. As a final solution (if needed) I'll check in with the factory.

    Interestingly the first I had of this kind (30 years ago) was also a model L, and had no serial # anywhere to be found on any part, only the case number. An extensive investigation by Michael Mohr (he told me that he searched for this one longer than any other he had searched for) came up with the fact that it was made some time in the 30's. He found the case number of the pianos on either side of this one, but was never able to locate this one. So it has remained a mystery as well.  (There is more to this story...)

    Curious as to others' experiences.

    The factory has been able to find me the serial number before with the era and case number!

    Daniel DeBiasio kindly looked this last one up for me and it checks out. He also informed me that (although labor intensive) it is possible to identify all Steinways from the case number AND the time period together (since case numbers get re-used over time).
