This insulator is quite unlike most Hemi/HGCO beehive insulators I have encountered, this one is much like the new style Hemi 21 with that skinny, narrow dome and body style. The colour is Hemingray blue, embossing is I / I on skirts and H on dome in huge prism embossing. Lots of bubbles and will make a fine addition to your beehive collection. VVNM to mint condition. Want a pic side by side with a regular light aqua HGCO hive? Just mail me and I'll send it. $10 + $7.50 shipping.
