This appears to be a Toshiba light bulb checker sign, but the details are unknown. Operation has been confirmed, but there is a break in the power cord as shown in image 11. The condition of the wiring is unknown, so please refrain from normal use in its current state. Use it for parts or repair the wiring before use. We are not responsible for any fires. We recommend enjoying it as an interior decoration without electricity. It is an old item, so there are stains, scratches, and dullness. Please note that the sign body is made of plastic, not tin. There is a lot of rust on the metal parts. The light bulb and miniature light bulb in the main image are also included. Please note that we will remove the listing if it sells on another site.
