Here's an unlisted U-1606 with an early incuse marking for the Rosenthal Porzellanfabrik (usually these are stamped. This is the first incuse marked [id=651976327] example from this manufacturer I've seen!). Exported to Argentina. This example made in Germany is unlisted and has a more pointed crown than other examples.

Small upper wire groove abrasion (seen in pic) and 2 tiny pecks and scattered light use marks. Easy VNM.

First email gets it for $50 plus shipping. Thanks!
