Bach Accessories – Master Mute
This is one of the earliest Bach mutes that I have ever seen. It is labeled as:
Vincent Bach Corp.
237 East 41st Street New York
This mute would date from the period of 1922 to 1928, based upon the factory address above. Vincent Bach had these manufactured by Joseph Rapuano at 222 East 105th street, New York City, NY who was building mutes and assembling French Besson “Fabrication” trumpets at this same time. Joseph Rapuano earlier in his career was the 2nd trumpet, Metropolitan Opera Company of Chicago. (reference)
From the 1925 Vincent Bach Corporation catalog (page 17).
