This insulator is still available as of Dec 14, 2013. This Hemingray blue color is excellent and the condition is very good! Only missing a piece of a drip on the rear side which also left a tiny bruise.

Embossing is:

(F-Skirt) HEMINGRAY / MADE IN U.S.A. (R-Skirt) No 18 (with a line under the o in No) Sharp Drip Points

Well, How about $10 plus shipping to a U.S. address?
