National PE-2057 Panasonic A strobe (flash) for film cameras, released by the former Matsushita Electric Industrial. Made in Japan with an auto-check function, allowing exposure settings using guide numbers. Power source: Uses 4 AA batteries Compatibility: Due to being an old-style general-purpose strobe, it is not recommended for use with digital cameras. Primarily used in combination with older film cameras. Comes with a dedicated case. Retro Antique Vintage I am not familiar with cameras, so I have not been able to confirm its operation. I will describe what I have noticed about the appearance, but please check the photos carefully and ask for additional images or questions if you have any concerns.
