This is just one dandy piece of candy colored glass. Photo shows a bit darker than it really is - passes light even better than it shows here. Colors range from intense yellow-green to patches of aqua, and heavy red-amber swirls waving about like tiger stripes. Condition is excellent, with only a small peck / bit of roughness on the rear wire ridge from when it touched another insulator while still hot. Embossed with only a "B". I took this one out of service myself out in the desert west of here. $35 post paid in US
