Streamline Art Deco Pen Holder and Calender from a Bank Counter circa 1920's

This is what I believe to be aluminum or an alloy of aluminum and nickel Art Deco Counter Calender and Pen holder from possibly a bank. I do not have the calender or the pen inserts for this piece.
The glass in the center is think and is not cracked and the over all condition is very good.
