I am in possession of a Regal Musical Instrument that belonged to my father it is a Tiple. He probably purchased it the early 20's or before in Chicago. I grew up listening to him play this lovely gem - singing old songs and silly songs. He performed at campfire at Camp Anokijij iWisconsin. I am wondering what is the value of this instrument. Does anyone have knowledge of this 10 string instrument? I do have a picture of it that I could post.
