Buescher trutone sousaphone

[sousaphone68]

The family of a deceased member of the band that I play in has donated his Bb Sousaphone to the band.
It is a Buescher trutone in silver plate the serial number dates it to 1926 and he acquired it in 1937.

The original mouth pipe is missing and a home made one has been used but with no tuning bits the sousaphone is very sharp.

The valves are in reasonable condition and the pedal notes are very easy.

Anybody got a mouth pipe and tuning bits that would fit this sousaphone?
