I have a vintage 1950's era Valiant Personal Calculator which is also showcased in the National Museum of American History - Behring Center. Includes plastic case, calculator and stylus.

Along with this sale is a Sterling No 565 Dial-A-Matic Automatic Adding Machine

Two historical pieces of history can be part of your own personal collection.

Both in working order.
