Bells are rose-gold or brownish-gold in color when polished.
Numbers to indicate size or the maker's name or initials may be found on some bells.
When in doubt, your bells are probably from this era.
Here are some key features of bells made in the mid 1800s through the early 1900s: Bells smaller than about 1 3/4" diameter were made in many styles. Petal bells have a distinct ridge or rim around the middle.
The throat (slit) across a petal bell should end in larger circular openings.
Throats on other bell designs may or may not have this detail.
Bells larger than 1 1/4" in diameter almost always have four holes in the base.
