This is a Showa-retro dial phone. Oki Electric 650-A1(B) It's a rare light blue color, not the typical black phone. This color was only permitted in limited locations back then. Therefore, the rare light blue color gives it a retro-pop impression. This phone doesn't have a box, but it's unused and in its original condition. The phone function can be used with analog lines or fiber optic lines. The original rosette (phone jack) from that time is included, but it can be replaced with a modular rosette upon request. This is a rare phone, perfect for your collection.
