Found in my parents' storage. The house was built in 1958. It was renovated in 1970, so it's likely this was removed and stored at that time. It could be used to create a retro atmosphere, such as in an old folk house. 【Outlet Specifications】 yamada mark (circle) 10A 250V ◯ Base Made of ceramic Round diameter: 57mm Height: 16mm The brass inside is slightly rusty and discolored. There are spots that appear to be unevenness in the ceramic firing. ◯ Black cover Likely made of Bakelite. Round diameter: Max 52mm Min 31mm Height 24mm There are some cracks and repairs. I have actually connected a cord with a plug to the base and used it to make coffee by plugging in a coffee maker. However, when using it in practice, it is necessary to have a qualified electrician thoroughly check its safety. I am not responsible for any issues. (The cord with the plug in the photo is not included) Please purchase if you understand that this is a used item that has been stored at home for a long time. Returns are not accepted.
