This is an Akai Electric metal open reel No. 7 made in Japan that was used in the 1960s.  It has a superb and striking design that is quite unique and thoughtful even today.
The AKAI brand logo is carved on the metal part of the reel and written in double font. The configuration of forming the reel by arranging the plates in two rows is quite innovative. Each side has a different design, and they are great. The other side consists of two types of multi-circle holes of different sizes, large and small, and has a new mechanical atmosphere design.  Once attached, you will get a cool and crazy deck with a mechanical atmosphere, and you can enjoy the joy of owning it, and of course, it can be attached to most decks of other companies.
