Here is a picture of something I recently acquired. I had never seen another, and any comments would be appreciated.
This was a catalogued ring-top model (seen in 1932 catalogue) but - as David mentioned - in uncatalogued colour for the Doric line. However, the colour itself *was* catalogued in that very same catalogue, for the Equipoised purse pens line: IIRC, this colour was called Borneo Pearl. A nice find!
