The Ohio Brass Antenna Coil Insulator, better known as the Christmas Tree. Also Submarine insulator. It does have a US with an anchor stamp on the base? I have had a lot of fun with this piece decorating it at Christmas. It is MINT, Measures 23" tall by 6" wide. A hefty piece! Making room for more glass! $150.00 plus shipping. Or delivery to Octoberfest in Richfield, or Springfield. This is a Centerpiece!
