Cornet Made By Boosey & Hawkes in 1977

This Cornet made by Boosey & Hawkes in 1977 I think looking at the code no 598760. Good all round condition.. The case has a bit of rust on the clasps outside and no key but otherwise is fine for the age. All valves & slides move well & it makes a good sound. If you would like to come and see it please let me know.
