The Clarendon upright piano was manufactured by the Haddorff Piano Company, which operated out of Rockford, Illinois. Haddorff was a prominent piano maker in the early 20th century and produced instruments under several brand names, including Clarendon.

A Clarendon upright from around 75 to 100 years ago—so roughly between 1925 and 1950—would likely be a tall upright model, often over 52 inches in height. These pianos were built with solid craftsmanship and were known for their rich tone and durability. One example from 1917 (serial number 75,337) was appraised in good condition with an estimated private party value of $250–$500, mainly due to its age and the fact that it’s an upright rather than a grand piano."
