Underwood Typewriter Guide

Historical orientation

The Smithsonian dates the introduction of the Underwood Model 5 to 1899 and describes it as the result of decades of typewriter development.

Underwood began producing its own machines in the 1890s after an earlier business supplying ribbons and carbon paper.

Olivetti acquired Underwood in 1959, so later branding and design can reflect that corporate transition.

Model families to learn

• Underwood No. 5
• Underwood No. 3 and No. 4 standards
• Underwood Standard Portable
• Underwood Champion and later portables

Identification clues

• Look for model numbers on the front frame or paper table.
• Standard machines may share a family resemblance while differing in carriage width and feature set.
• Serial-number location and range must be matched to the correct model series.

Before buying

Ask for the serial number, a current typing sample, photographs beneath the ribbon cover, and a clear explanation of any service. Compare the exact family rather than treating every Underwood as equivalent.

Useful comparison terms

Add the model, body generation, color, keyboard language, case, working status, or service terms to your search. For electric machines, include the exact generation and correction system.
