Does anyone know about H.B. Jay Co? I have a silver plated soprano (with, again, the obligatory smelly, purple lined case). The bell is nicely engraved with some flowery looking pattern and then "Columbia, H.B. Jay Co. Chicago". The serial number is 158644. It is also stamped Low Pitch. The tone holes have the tops that are beveled in as such: / \
That is the best I can show using keyboard characters :)
Any help is appreciated!
