Here's a knock out color for your light box- a glowing Medium cobalt blue- in some light has purple tones which gives it a cornflower hue- CD 578.7 from Belarus. Comes with the scarcely seen PNT crown marking and II. There is a half fisheye on the dome, 1 inch inner skirt roughness and 1.25 inches of shallow base chipping, bb ping on the shoulder and a few teeny pinpoint tic marks. As you can see it is a real beauty for your collection!

For a close-up of the PNT marking [id=325740464].

Priced to fly at $50 with free shipping in US and reduced to Canada. Thanks!
