Vintage NK Bell Japanese Metal Jewelry Music Trinket Box WORKS TESTED For Sale

Vintage Japanese Metal Jewelry Music Trinket Box WORKS TESTED. NK Bell stamp on bottom (see pictures). Was told its from post WWII Japan, and the mountain in the back is Mt Fuji. Was at one point painted, but time and use has worn that down (can still see some leftover paint on it). Measures roughly 7 inches by 4.5 inches by 2.5 inches tall. Is pretty dirty from storage. Music box works, lock turns but doesn't firmly lock in place. Hinges work fine. Any additional questions/requests, please don't hesitate to ask. Thanks!
