Badge of Rear Admiral Oishi Shokichi https://asiamedals.info/threads/naval-academy-graduation-badge-of-rear-admiral-oishi-shokichi.27098/

 

Interesting badge without depressed pebbles (known in Japanese as Nashiji 梨地 - pearskin finish) and slotted rays.

Note that badges made by Miyamoto Shoko and Hattori workshops have convex pebbles.

In every other respect badge is identical to the examples given above.

 

Another badge without slotted rays but this time with pebbles.
