Collectible Antique Phone Mouthpiece

Description

Brass Antique Phone Mouthpiece
NOTE:  I have been informed that this piece is a mouthpiece from a early phone, possibly from an erlyiest wall oak phone to the candlestick of the teens / twenties.
Up for auction is an
antique Brass Mouthpiece
from an early phone.  According to one helpful Ebayer, this mouthpiece is from an antique phone, possibly from the early 1910s or 1920s.  It is made of mostly brass but is apparently
missing a cone shaped piece
.  There is a tag on the piece but try as I might, I could not decipher what was on the tag.  The piece is about 3 1/8" wide and about 2 1/2" high.  It is in good used condition but has a lot of patina.
Thanks for looking
