While checking with the factory, there was one Concertina in production nearing completion.  The piano would then be crated and flown to the airport where we would pick it up.  This process, normally quite smooth, was held up because of new enforcement of an old regulation called the Lacey Act.  I became an instant expert while naming the wood species and quantity of all the different woods used in the construction of the piano.  I had never been asked down to the species.  Still, the piano was well protected during the efforts of Customs to comply more than we'd ever complied before!
