>I looked in the books and saw what the round bottom looked like and thought -
that's a lost cause.  About 2 weeks later at a local flea, I found the round
bottom in the bottom of a box - 25¢.

Wish I had found the same sort of price, but I had a #66 beader with the
straight fence.  Kept my eye out for the curved fence.  Never found an
orphan curved fence, but one day I found an even earlier (japaned) 66
with a curved fence.  Oh darn!  I have to put up with two #66 beaders!
