Hello! I recently found an old Copal flip clock in Japan in an old house I bought. It's showing its age but works and looks like a 201, although the label is old brown paper. I carefully opened the back and found no other markings. Chatgpt just says it could be pre-101 or a poorly documented early variant / likely an early transitional unit before model standardization. Just wondering if anyone knows what I actually have and if it has any collectable value. Thanks!
