I have owned this antique Glass soda fountain straw holder for decades. I only have room for 1 now and I have 2. There are two patent dates on metal lid top at handle. One is Jan. 15, 1912 and the other is Aug 22,1915. Perhaps one is glass and the other the metal holder part. The glass is made by King Research. It has what I believed a hand blown glass circle on bottom. It is very heavy weighing in at a little over 3 pounds. It is in excellent condition. There is one small dent in top and a small amount of rust stains in inner basket. The basket weld is good. Will be mailed with insurance.
