I purchased a ( I think I would call it) Carnival Glass bell. Not the deep green and purple I usually think of when speaking of carnival glass. This is more of a corral color to blue. It is a simple hobnail, with one oddity. I found inside the bell where the clanger attaches the word FENTON and 1980. I have other hobnail bells but none have these words molded into the bell itself. Is this an older bell? Is the 1980 the year it was made or is it a mold number? I would appreciate any input. Thanks Holly B.
