when looking at the engraving on the bell, the lowest wire keyguard on the bottom left side would be in a mercedes 3-way shape, as opposed to a T shape for Buescher, which is what this one appears to have. correct me if I'm wrong...
from his flickr site:
if the Union stamp serial number is correct, this would be early 1900s. Is there a serial # on the back side below the thumbrest, and does it say Low or High Pitch?
