My Yamaha Maestro Bb cornet was purchased on 12 November 1996 from Myatt's Music Shop in Hitchin (north of London). The instrument is the model known as YCR 6335H. These details are imprinted on the casing of the middle valve. The unique serial number of my cornet is 201057. The word 'Maestro' is printed on the mouthpipe. At the base of the second valve - on the reverse side - are the words 'Yamaha Japan'. There is no engraving or printing on the bell.
