This is a Japanese-made strobe that allows for both auto and manual settings. There is some soiling due to age. Since the operation has not been confirmed, please consider it as junk. It will be shipped via Yu-Packet Post Mini with simple packaging. - Brand: National - Model: PE-1400 - Auto Setting: ASA 100 I am not familiar with cameras, so there may be errors in the description. Please make your purchase based on the photos. I hope someone who needs it can make good use of it.
