Standard Folding & Corona 3 Variations

Updated: Jan 7

This is my attempt at cataloging the easily-discernible differences among Standard Folding Typewriters and Corona 3s. Typefaces (Corona 3)

  • Pica (available with Standard or Gothic numerals)

  • Elite (10 pitch; 12 pitch by special order)

  • Medium Roman

  • Italic (rare; only a few are know to exist)

  • Double Gothic (very rare; only one is known to exist)


  • Apothecary (available on every model, including the Standard Folding)

  • Mathematic

  • German, French, Spanish, Greek, Russian, and more


  • Decals on Standard Folding Typewriters varied between Old English type style and Roman type style. The Roman type style logo is very rare; only a few are known to exist.

  • Early Corona 3 typewriters have “Standard Folding Typewriter” in parentheses beneath the primary Corona logo. These include both the "pivot arm segment" and the "bearing arm segment" variants.

  • The earliest Corona 3 typewriters lack the pigeon logo on the paper table.

  • Corona 3 typewriters produced in 1915 shortly after the company name change have “Incorporated” written out beneath Corona Typewriter Company on the front of the frame. Serial numbers tend to be 52XXX for this variation.

  • Improved Model 3 typewriters made prior to the Smith-Corona merger have “Corona Typewriter Company” on the front of the frame, and post-merger typewriters have “LC Smith and Corona Typewriter Company” on the front of the frame.


  • Nearly all of the Standard Folding Typewriters were manufactured in unpainted aluminum. There is at least one early example that was painted black.

  • All Corona No. 3 typewriters and Improved Model 3 typewriters were painted black at the time of manufacture. While Corona experimented with a woodgrain variation, the woodgrain version never reached market.

  • Corona Specials were offered in red, green, and blue. They were also offered in black with gold, green, blue, or black crinkle paint around the Corona Special logo.

  • Corona Specials were occasionally offered in white or tan, but such color changes were made at the dealer level.

Foreign Name Variants

  • Albus – manufactured by licensee in Austria for German, French, and Austrian markets

  • Azeds

  • Atlas

  • Emka

  • Engler

  • Franconia

  • Proteus

  • Piccola – rebranded for sale in Austria and Germany

  • Kopoha - rebranded for Russian market

  • Coronet – rebranded Corona Special offered by Harrod’s Department Store in the U.K.
