Exposure meter for NIPPON KOGAKU JAPAN film cameras (SP.S3.S4.S3M), with diffuser metal plate (for use in strong light). - Brand: NIPPON KODAKU Selenium (no battery required) Condition: Exterior has some scratches and dirt. Lid opens and closes ok. Each ring operates normally, other functions untested as there is no camera to test with. ★ The needle moves when exposed to light (photos 11, 12, 13, 14, 15), but accuracy is not guaranteed. (Working condition models can be purchased at camera stores for around 30,000 yen.) ★ This is a very old item, so it is being sold cheaply as junk. See photo 15 for reference from another site. - Accessories: Diffuser Thank you for viewing.
