c.1915 Columbia Koa Soprano Ukulele

If you've been following this blog you may know that I have a sort of "thing" for koa. It's an incredible tonewood. This uke is not only entirely solid, antique koa, but the neck is simply beautiful flamed tigery greatness! This is a Columbia brand "Hawaiian Ukulele" -- probably made in Chicago -- and is built rather similarly to early Hawaiian ukes, save that the neck is a mainland-style dowel join as opposed to a Spanish heel. The body is 2" depth all around with a smaller-than-normal soundhole which gives it a responsive but yet warm and jazzy tone, as opposed to the truly snap-tastic tone usually heard on mainland ukes. Why am I telling you all this? Because I think this shows that this is an early-on mainland design, probably c.1910-1915. It even has its original wood pegs (which are quartersawn oak!).

Great pumpkin color.

Flame! Ebony nut.

Flame! Ivoroid or bone dots (not sure).

Label and simple rosette.

Curious bridge with triangular-shaped saddle.


Here's "Tiger" from the side.

And as you can see, the original finish cleaned up very well!

The flame in that neck kills me! It's also a nice, cozy shallow D shape, too.

Original quartersawn oak wood pegs!

Back.

Back grain is nice, too! There's a repaired hairline on the lower bout (try and find it).

Tickles you, doesn't it?
Another 3/4.

And another "early" pointer? The sides are made from one long piece of bent koa -- something manufacturers rarely went to the trouble to do in the much more mass-produced uke era. Looks great!

I'm just wondering, what's this thing worth? I've seen a few numbers online ranging from $150 to $600. Mine appears to be in better shape than all of then, though. Any idea on value?
