Lefty is Amethyst (only one i believe) Right is Green with Amber

Both are f-Crown PATENT / DEC 19 1871 r-Crown 3 r-Skirt A (well the purple one would be if a chip didn't take it off)

Need an olive amber blackglass one to complete the line up if anyone knows where it (or the specimen) is I'd love to hear from you (especially if you're willing to let it go =p even if not i'd love to see a picture =)
