'Maker': 'JOHN GREY'


Type:  F/Bb compensating double,

incorporating the Paxman 'Studenti' 4th valve


'John Grey' is a 'stencil' name; the horn was

made in Italy, probably by Kalison, Orsi or

Rampone & Cazzani.  


 Similar fictitious maker's names often found on this

model include: Alliance, Anborg, Buisson, Getzen

and Viking; there may be others.

compensating double horn, dating back to at least

65 years ago, incorporates a 4th / 'change' F-Bb

valve that is nearly always notorious in its lever's rather

inconvenient placing for 'small to medium'

sized hands. However, the tubing design of this

horn incorporates a different 'routing' of the

tubes near the 4th valve, so that it can be reached

much  more easily by the thumb

This re-designed layout makes the horn quite similar to

a Paxman 'Studenti'.


Bore / Throat: medium

Alloy: unlacquered yellow-brass; nickel silver rotor caps

Bell flare:  fixed

Valve compression: good on the Bb side; 'OK' on the F


Weight: 2.44 kg

Mouthpiece: PHC silver plated 23 cup with gold plated



Visual / cosmetic condition: the horn ‘has seen a lot

places,  but is in good mechanical condition. This

is reflected in its very inexpensive price.


Weight: 2.49 kg


Further details: a useful, basic 'no frills' beginner



The horn comes with a hard case that is quite bulky and

heavy; various inexpensive alternative options are
