I think this piece was made in the mid 1920's. There are a few flea bites or manufacturing flaws on the base of the piece possibly from movement see last two photos. Some light gold gilding wear and the other expected wear marks from age see photo 6 and use please see photos. You just don't see this pattern very often if at all!
