It is a WWII era Columbia slot machine from Groetchen Tool. When you insert a dime, it drops right thru to the return. Pull the arm and hold it down and the wheels spin and individually come to a stop as they should. The top round piece under where you insert the coins doesn't do anything.
It is a great machine with a. Great look, it just needs a little fine tuning. It measures 13 X 12 X 9 not including the base, arm, or where you insert the coin.
