    A lovely example, recently serviced, of the C.S.

WILLSON Geyer-style double horn.  

  Although this superb model is sometimes regarded as a 'large' horn, the bore of its central cylindrical tubing is 11.85 mm, so, smaller than e.g. some well-known horns such as Conn and Holton (11.89 mm bore), Paxman (12 mm) and of course Alexander and Finke (12.1mm).

    Willson horns are renowned for their 'Rotax' valves, which offer less resistance and a smoother air-flow than conventional rotors. 

  Overall, this is a beautifully made, very responsive horn with an even sound throughout the whole range and a wide palette of tone colours. 

'Swiss precision engineering’ at its finest!
