it's definitely worn, ed, but when i sighted down it it's still well-shaped
for the center bead.  it's still tight in its dovetail, and none of the
individual pieces are loose at all.

the iron is worn worst; it might be time to cut a new iron and keep the old
one on the shelf.  however, for the nonce i'll just sharpen the old iron
and give it a try.

oddly enough, the wedge is twisted above the plane body, but it fits nice
and tight.  i've not seen *that* before.
