Going through the pile

Will you look at this? I spent some time sorting the koa sets I have on hand, and found 17 of them! A couple are big enough for concerts, the rest sopranos. I had real trouble matching tops and backs with sides. And I found that some bookmatched pieces actually weren't bookmatched; they came from the same board but there had clearly been a couple of slices taken out between them. 

I got them fairly cheap and a couple of sets are really good so I won't moan too much.
