This is a pair of Hemingray green glass insulators. One is marked Hemingray 42 on one side and Made in U.S.A. on the other. The second is marked No. 40 on one side and Hemingray on the other. The 42 is slightly larger, 4 1/4" tall. The 40 is just under 4" tall. Both are in very good condition with some chips and nicks around the bottom rim. The 40 has more damage as you can see in the photo of the undersides. Please see my other items for more Hemingray insulators. MBR.
