I've just been given an old chromatic harmonica, and would appreciate any info anybody might have. On both sides it has stamped "THE BANDMASTER DE LUXE CHROMATIC" To either side it also says "FULL OCTAVES" and "ALL SHARPS AND FLATS", and to the left and right, near the bottom, it says. "MADE IN GDR" and "SEYDEL SYSTEM"
Now, obviously, some of this is self explanatory, but I would like to know how old it is likely to be. Also any tips on cleaning in order to make it safe to play. Not even sure if it's actually ever been played!
Many thanks!
Paul.
