These two were found in a hole buried with several other insulators, likely put there by a lineman long ago. They are both shaped differently, one more a CD 145 shape, the other a CD 143 shape. The more 145 shaped is very crude - the base is egg shaped instead of round, and the glaze below the wire groove is splotchy. The C.P.R. incuse on the top is more of a block style lettering then the other. Does have a wire ridge and base chip. The other is VNM! Asking $3 each, or $5 for both, plus actual shipping. Email with your address for shipping quote. :-) Satisfaction guaranteed, or your money back upon return (minus shipping, of course) Thanks!
