Here's my latest CREB beehive addition: a nice junky piece with a big, solid band of milk around 3/4 of the insulator along with a band of carbon below it that spans the same circumference. As to the horseshoe shaped area on the photo, it is a internal fracture that I believe was caused by tightening the piece too much onto the pin. The "minty" types might call it damage, but I call it character!
