Check the listing for details. CA Seydel Sohne Mini Harmonica KohiNoor Charm Antique Chromatic Slide 1.5". Made in Germany. Listed at 199.95 USD. Antique C.A. Seydel Sohne Koh-i-Noor Charm Mini Chromatic Slide Harmonica Germany. The only info I could find looks like it was made in or around 1921.One side reads," C.A. Seydel Sohne Made in Germany". The other side reads, "Koh-i-Noor Germany Trade Mark". Measures approximately 3/4" x 1 9/16". Item has been used and does show wear. Still plays and sounds ok to my untrained ear, but may not be perfect, of course. Missing the sliding bar. Retains some of its original red paint. Has been lightly cleaned of years of dust, but still has dust/debris in nooks and crannies. Metal has scratches/marks/patina. Item is generally clean, but as this is a used item, should not be considered pristine and new owner may wish to do further nook and cranny cleaning/dusting/polishing. See pictures for more details.
