I believe this item is from the time of World War II. Receiver for communication equipment. Type 1 Cho-Gata Receiver, manufactured in 1941 (Showa 16). Perhaps a collector's item or museum piece? This is the same type of equipment used in Godzilla Minus One, immediately after the war, when Ryunosuke Kamiki boarded the Shinden. I found it while organizing my storage. What do you think? It's an original, not a replica. Thank you.
