I recently acquired this lovely mother of pearl eyedropper pen with a screw cap, which I understand is a little unusual. There aren't any markings on the pen though - I was told that in the past "someone" figured out what company put these out and wondered if anyone remembered that? I attach a few pics of the pen. I haven't received it yet so these are pics from the sale.
Thanks in advance for any info anyone might have? I would love to know who made it, and in what decade?
