This is a 103 with lots and lots of history.
It is not new! We think it dates from the 1920s, possibly the 30s.
This could even have played alongside Dennis Brain!
Like a vintage motor car this horn is not without its idiosyncrasies but makes a beautiful rich sound. With regular tinkering with oils and greases etc this still has plenty of nice playing ahead of it.
Who will love and cherish this instrument next?
