Here's what I thought was a plain old 36-19 no-name until I noticed a couple of milk swirls in the outer skirt. I cleaned it up and saw that the glass had a cloudy/opaque appearance. Put it in front of a lamp and saw that there is milk swirling throughout. Got out my trusty flashlight for this shot. Has anyone out there seen this milk swirl effect in these? No mention in the PG about it. Thanks for looking.
