Ca. 1885-93. Truly antique four-bar model by the earliest American manufacturer of the autoharp that was later marketed with great success by the Oscar Schmidt company. Zimmerman's 1882 patent on the label actually refers to a somewhat different instrument. More info.
In excellent structural condition and fully functional. For the autoharp enthusiast, a great item for display or play, great for tuning to a specific key for specific songs. Has original label. Cleaned, polished, tuned and tested, not cosmetically restored. Would benefit from new strings. Sold as-is. No case.
