Adler Typewriter Appraisal

Adler Model No. 7 Typewriter

This is a vintage Adler Model No. 7 typewriter, an iconic piece of early 20th-century German engineering. The machine features a distinctive thrust-action striking mechanism where type bars slide horizontally rather than swinging vertically, common in 'Empire' and 'Adler' designs. It is housed in its original solid wooden carrying case, which shows signs of aged patina and light surface scratches. The typewriter frame is constructed of heavy cast metal with a deep black enamel finish. The gold-leaf and red decorative stenciling remain remarkably vibrant, clearly displaying the 'ADLER' brand name and the manufacturer details 'Adlerwerke vorm. Heinrich Kleyer Aktiengesellschaft, Frankfurt a.M.' The specific model designation 'Mod. No. 7' is visible in yellow lettering above the keyboard. The keyboard consists of three rows of circular keys with glass tops and metal rims, showing a character layout appropriate for the period. Notable features include the dual ribbon spools mounted at the rear and a manual carriage return lever. The condition appears to be good for its age, with some visible dust accumulation and minor oxidation on exposed metal parts like the platen knobs and type bars. There are no obvious signs of major structural damage, though the rubber platen and feet may have hardened over time. The craftsmanship reflects the high quality of early German office machinery, dating this piece approximately between 1900 and 1920.
