Hi junk in glass fans! We all know Hemi 40's are a plain jane insulator that rarely has anything interesting to offer right?I guess this is the 1 out of 2,000 that has something to offer! Pitchfork. Most firmly embedded in the domeside is a great looking 3/4" long X 1/4" wide tapered and jagged white rock right where it can be seen best. How many of these ya think you're gonna find? This is a N & S find.
