Fenton Blue Carnival Hat in Holly Pattern

This is a Fenton carnival glass hat in the holly pattern. Part of me thinks this is real while the other thinks this is a reproduction.

There are two things that make me think this is a reproduction. One, the base is an irregular shape. I have seen a couple examples online and those bases are more rounded. Two, on the inside at the bottom there rough bumps that dont appear to be part of the pattern.

Let me know what you think. Either way, I think this a nice piece but I would like to know if this might be a repro.
