Will let the buyer make the judgement call as to or not this insulator is a two tone. The dome down to the somewhere behind the lower WG bulge I'd call milky light blue or blue aqua. There is also some light milk swirling on the left side of the skirt. The EIN the embossing comes closest to is 350. All except the number on the front crown. There is no number (shop) on this one. In its place is a big glass dot. all the embossing is easy to read. The Pat March 20 1870 embossing is only slightly difficult to read. At least to my eyes. Could be the effects of all the milk behind. You certainly will not have to use a black back ground like I did in my pic to know the milk is there. When I first saw the piece I held it up to the light only to see whether or not there was glass sickness. The answer was to my question was NO. The whole insulators surface is shinny.

This insulator also has some of the most pronounced mold line I have ever seen on a 126 creb. The condition is one flea bite right behind the left side mold line at the base of dome.

Have this insulator on your door step in 2-3 days once a one time payment of $35.00 is made. Add $5 if your address is north of the U.S. border. I accept Pal Pal in a non-fee mode or personal and money order checks as payment. I will combine shipping and give shipping discount other insulators I presently have listed for sale here at Icon. However, you better email me about this insulator first. Being I have a first email policy you wouldn't want this one to get away while you are shopping for more glass for your insulator fix!!
