c. 1896, trademark name (1901) of a mechanical player-piano device using perforated rolls of paper, from piano, the ending perhaps abstracted from viola and meant as a diminutive suffix.

brand of shoe polish, by 1904, from shine in the "shoeshine" sense + commercial suffix -ola. The company that made it dates to 1877 and seems to have ceased production c. 1960, but by then the word was proverbial for what you don't know something isn't.
