9-1/2" diameter; ~1" deep; 272gm; it came in an old, stained, broken-lidded box without any mark ; too big to be original, IMHO.
Well and plainly signed on the image, lower right; jungin mark (I hope) very small roughly centered on the back (may be inverted);
No stand or other support. Hammering distinct on rear, which is smooth; looks to be a spherical section.
The inner surface appears finely 'frosted'; toning (and fingerprints) obvious, particularly at rim area; ordinary tarnish on the back.
If there's a process name for the 'frosting' I'd like to know what it is.
The name of the artist, where and when he worked, and/or any other significant details/history will be most welcome!
