Here is a CD 143 insulator that's somewhat hard to find in this smoke color. Its EIN [010] embossed on front G.N.W. Pic taken outdoors and its a little more smoke color than pic shows. It can use a little cleaning. For this old timer it has a crown ding in rear, at lower wire ridge by left mold line a wee ding, and base has one small chip at right mold line and two flat base chips in rear. The base has a little excess glass which is nibbled making it look worse than it is. Base pic upon request. Trying to be accurate here but it displays pretty much mint from front. Good solid piece and asking $300.00 U.S. + shipping. I accept PayPal in family friends mode and also checks. First email as usual. How about $275.00
