Vincent Bach 190M37X B-flat trumpet

† Bach bell models:
When Vincent Bach began manufacturing instruments in the early 1920s, his experiments resulted in over 70 different trumpet bell models, each numbered according to the ‘mandrel’ or mould it was shaped upon. By the early 1950s certain standard models had emerged, those we now know as #37, #43 and #72. The model #37 is regarded as the standard all-round bell, suitable for all styles; the #43 is broader, brighter and more open than the #37 (suitable for jazz lead); the #72 has a strong, powerful sound, darker than the #37 (but takes more effort to play than the #37 or #43).
