Loetz PN II-8231 shade in PG 2409 ca. 1912

Adding to my PG 2409 collection, I found this PN II-8231. It is listed in Lnenickova's reference as being made in PG 2409 elefenbein mit 5 moosgrun leaves, 10 ruffles and innen silber. It is 4.75" tall x 4.25" in dia. My amateur investigation suggests that the threads of the leaves are pulled in a manner that seems to be unique to Loetz: that is, they are pulled from below the fitter rim.
