Here is an [030] beehive with a nice extra - a large 3/4" long chunk of firebrick! This insulator is green aqua leaning toward light green, has a backward "6'" or "9" on the dome, but the mold has broken away and made the number look like a blob. There is another piece of firebrick in the inner skirt. This insulator is V VNM. $22 postpaid. Please click here for close up of firebrick. [id=154025638]
