※ Ships today. I am selling a Kikuchi-made 4-transistor intercom kit. This was a technology and home economics practical training kit from the Showa era. Perfect for Showa retro collectors! Please be aware that there are names written on the box and the machine. Since I haven't confirmed the operation, I'm selling it as a junk item. I am also selling other Showa retro items. If you purchase them as a set, I can offer them at a lower price, so please consider it. #kame_Showaretro Please feel free to ask any questions. Thank you.
