Found this while cleaning. It's an instruction manual for a Showa-retro National (now Panasonic) lighting fixture. It's a single sheet. There is age-related staining and yellowing. Please check the photos. This is an old item from several decades ago, so please refrain from purchasing if you are sensitive to such things or are looking for a perfect item. I have inspected the item, but please forgive any oversight. Please read my profile before considering a purchase. I'm very sorry, but I will ignore questions about how much I can lower the price. I would appreciate it if you could rate the item promptly upon receipt. It will be shipped via Nekopos.
