This is a fairly plain B in a decent color, but the odd part is the wire groove. The mold obviously had been changed to make for a deeper wire groove, which led to a rough groove, with small vertical ridges, evenly spaced, around the entire insulator in the groove. I suspect this would have been fixed in a later mold, because I haven't seen many like this, and my father had over a thousand B's! Has a thumbnail sized chip on the rear inner skirt, and a few tiny tiny pecks here and there, but the color, wire ridge, and the few amber whisps make it a nice, interesting piece. Asking $7 plus actual shipping!
