Tuba. Nominal pitch: 16-ft C.

Technical description: Brass; probably altered from original design. Fitting for music card holder. Valve type: 3 Périnet valves, bottom sprung, alignment by key on piston. Repair History: Appears to have been modified from a smaller instrument, possibly a saxhorn contrebasse in E♭, by the addition of tubing between the mouthpipe and the main tuning-slide. The two loops in this section are not usual in saxhorns; the three ferrules in the loops are of different patterns (1st long & curved, 2nd plain, 3rd embossed); the tubing to 3rd valve tuning-slide interferes with 1st valve tuning-slide, stopping it 17mm short of full insertion (the 1st valve tuning-slide seems authentic, legs 113 & 115.5mm); the 2nd valve tuning-slide legs too long to allow full insertion, the longer leg by 17mm, the shorter by 9mm. (The 3rd valve tuning-slide seems authentic).
