Thanks, those came through fine.
As the white goes to the edge it can be one of two finishes:
1. Opal flashed glass - this is a glass surface, not sprayed, so will be very shiny.
2. Enamel sprayed - this will appear duller than a opal glass finish.
However, looking at the photos, I would say it was spayed enamel and then silk-screen printed with the Cordon pattern. If it were opal-flashed the colour would be a lighter-grey and not the brighter finish exhibited on yours.
But for all that, it's still quite uncommon and probably an earlier model.
