The Seiko Executive Egg ,It’s a plastic egg mashed up with a voice recorder. Because it’s from the early 1980s it records the voice using a tape recorder head on a magnetic disc much like those used in floppy diskettes.
The model is Talking Egg (TE 100) and it was made in Japan. The instruction booklet and warranty show the address as Seiko Instruments U.S.A. Inc. Consumer Products Division, 2990 W. Lomita Blvd, Torrance, CA 90505.
It’s a rare 35+ year old device you can’t buy any more and whether it was made by Seiko or Techmoan Electronics Corp .
It’s likely that the word Sekisui printed on the base refers to Sekisui Plastics of Japan who could have manufactured the outer casing.
