Besides Alley, there are a few lavender-based Akro corks, if you want to count lavender. Ummmm. I have a few purple pelt slags of the feathered variety -- some dark purple, others ranging up to lavender. And I have a couple of white-based WV swirls with purple ribbons, but I've seen them identified as both Alley and Ravenswood, so I keep them in my Puzzle Box.
Do you mean just machine made?
