Japanese? Lacquer-Faced Dragon Gong, Grecian Key Border

~10 1/2" diameter, ~1 1/8" wall, ~17 oz.

The Dragon has 3 claws...but sure looks Chinese to me; hence the query about Japanese origin. A copper alloy (bronze/brass) with a slightly domed/convex face; an acid-etched image (I may be wrong about the lacquer); the inner edge of the wall has a narrow (<1/8") triangular bead applied, to enhance its resonance, I believe. There are 2 holes ~5 1/2" apart through the wall, nearer the face than the rim, for hanging; pic 4 shows light passing thru them. It is hammered, 'tho the peens only show, slightly, on the inner face.
This thing is pretty dirty but I believe I can greatly improve its cosmetic appearance without damage to structure or finish. More pics after the work is complete. Thanks for lookin'!

 

Very cool,but getting my head around age,authenticity & value for Japanese & Chinese antiques has always eluded me.With 1.4 billion people making a million antiques a day-how can you keep up ?
PS-This does,IMHO-look old to me.
