Nice arc embossed TILLOTSON. Embossing is a little weak but when you pick it up and look at it, it's pretty easy to read. But the color! Personally I'd call this about an Ice Green perhaps leaning towards the Light Green side. Unfortunately, there is a chip on the wire groove (see photo) which is right in front... and a little minor scuffing below that. Parts of an open bubble on the rear. I'm not a threadless collector, but this seems like a neat piece!

UPDATE: A little cleaning with muriatic acid helped clean up some of the browning around this chip. While of course it doesn't decrease the physical damage, it definitely makes it display better! For a view of the "new" insulator, take a look at this [id=164067095; new picture]. Much better? $375 plus shipping. OK, lots of lookers but no takers ... So, how about $335?
