This 10 string harp guitar has no markings no it, i.e. no maker’s label, stamp, signature etc.
Probably American, likely a one-of-a-kind made by someone we’ll never know – but it’s very similar to the 1860 “Renaissance” Martin harp guitar that’s well documented.
See/hear the video of this guitar being played:
