£1,590.00
MAKER: HAWKES & Son
MODEL: Class A 'Excelsior Sonorous',
converted/adapted from a
Hawkes & Son piston horn whose
valves had worn out beyond
affordable repair.
Serial number: 60138
Year of manufacture: 1928-1929
• WEBB/HALSTEAD crooks for F, Bb and C alto;
PAXMAN Eb crook.
These four 'master crooks' can be seen, with
the horn body, in photo 5.
• FOUR numbered couplers by Nicholas Perry:
1) very small; 2) small 3) medium 4) double
• Custom-made extension shank, slightly angled, to
lower the pitch of the longer keys to A 430. This can
be seen in photo 2, in combination with the F crook
(a John Webb prototype).
• The crooks and couplers used either singly or in
combination will give the following keys:
C alto; B alto; Bb alto; A alto; Ab alto; G; F#; F;
E; Eb; D; C basso; B basso; Bb basso.
• The upper tuning slide's outer receiver is
removable, so can be replaced by a sauterelle
(a piston valve set, not supplied) in order to use the
instrument as a French-style valve horn.
• The internal taper of the horn's crook receiver is
compatible with old-style Paxman crooks (1982-
1990s) and Webb-Halstead crooks and/or couplers.
The photos can be viewed in greater detail
by opening and saving them.
