E269 Valve Trombone, Tenor in B-flat
Valve Trombone, Tenor in B-flat, Fratelli A. M. Bottali, Milan (late 19th century).
Identifying mark(s):
“(Trade mark) / PRIMARIA / PREMIATA FABBRICA / FLLI A. M. BOTTALI / MILANO / (ITALIA) / (star) / (in cartouche: MARCA / FERDO ROTH)” is on the bell.
Description:
There are 3 mechanical rotary valves, side action, with round, mother-of-pearl touchpieces.
Materials:
Brass.
Notes:
There is doubt as to whether the tuning slide is original or that the entry tube with the valve assembly belongs to the bell. The strut-plates and the ornaments on the struts are shaped alike, and perhaps both parts are Bottali parts, but the tube exiting from the valves does not fit the end of the bell tube. Doubting the singularity of the instrument, the length measurement might not be significant.
Measurements:
Total length of tube: 254.6 cm.
Bore at the beginning of tuning slide: 1.25 cm.
Bore at valve-slide 3: 1.3 cm.
Bore at the end of the exit tube: 1.1 cm.
Bell Diameter: 17.5 cm.
