Here's a wide groove signal that has a lot of milk swirl action going on. I have other pics besides this underlit one, just ask for them. In regular light, it takes on a cloudy appearance. After cleaning this piece when I first got it, I thought that this was just some stubborn film, but discovered it was loaded with milk swirls. The embossing index on this is [110] and the condition is a few ticks from mint with a little insignificant micro-flaking along the outside base mold line mentioned for accuracy. Unlisted color....could be an unlisted EIN because there is no dash after number 38. Very nice piece. $75 + shipping. E-mail for more pics or if there are any questions. Thanks for looking.
