Lot of 3 brass instrument mouthpieces, 2 probably trumpet.  1 probably tuba.  Tuba has no markings.  Trumpet are stamped "LYLE 7-C" and "MADE IN WEST RN-GERMANY" (E is probably worn off) and "VINCENT BACH CORP 7C". No dot after corp, whatever that's about.  This one appears to have electrical tape on it.  Probably from 1960s-1980s based on when my uncle performed.  See images for condition and measurements.
