Antique Lightning Rod Weathervane Stained Glass Insert

This is a vintage cast iron lightning rod weathervane. It is 23 inches long. It has a ruby red stained glass insert. The insert is 2 1/2" x 5 1/2". The design on the insert is frosted white and etched in the glass. T is some rust stain around the glass. I did not try to clean it, did not want to damage it. The cast iron is a little rusty but not bent or broken. Thanks for looking.
