The ukelin is a bowed psaltery with zither strings made popular in the 1920s. It is meant to be a combination of the violin and the Hawaiian ukulele. Nice condition, working with no missing strings. It is wooden and has enameled folk art flowers around the center. This piece says Colombina De San Juan. It is 15" long and 8" wide. I understand this is a difficult instrument to learn to play. It dates to 1950’s. I am uncertain of the maker. The History explains the onset of the Ukelin.
The history of the ukelin is hard to trace, since there were several instruments resembling the ukelin that were produced in the 1920s. Paul F. Richter filed the first known ukelin patent in December 1924, it was granted in April 1926. The Phonoharp Company, which merged with Oscar Schmidt, Inc. the same year, began producing ukelins in 1926. However, an instrument greatly resembling the ukelin had had its patent filed in 1923, a year before Richter filed his; yet the patent, filed by John Large, was not granted until after Richter’s patent had already been given. Another similar instrument had a patent filed by Walter Schmidt in 1925. Because of these patents filed one after the other it is unclear who really invented the first ukelin.
