yeah, I kinda agree about the calling it a uke thing. I think allot of people are calling things "Ukuleles" on Ebay, because it is becoming the latest "Fad" instrument. Kinda like it was in the 1930s. Their new popularity is a draw for sellers to list things as Ukuleles, even though it isn't. That is most common with Banjos. We talked about that some in another thread a week or so ago. Many sellers trying to sell vintage low end banjos as "Banjo Ukes".
As far as the thing on the link I posted. Im not even sure it is an instrument. Kinda has some aspects, bucket and headskin, strings, what looks like some sort of bridge. I don't see anyway whatsoever to adjust the tension of the strings, and how you would even play two vertical columns of 3 strings, I have no idea. Awkward at best. But, still kinda cool, especially if it is a vintage instrument. But that said, it may very well be something someone dreamed up and made to "appear" as a crude, vintage hand made instrument but to be used as a decor piece..
Anyway, that is why I posted it, to see if there are any vintage instrument collectors that might know what it is exactly..
BTW: after looking at it closer. The strings on it really look like fairly modern twine that has been stained to "appear" old. Might even be a polyester twine..
