Lightning strikes may no longer be a logical analog for matching broken points when there are many people on many screening tables...It's just a matter of
everyone displaying their finds at the end of the day..
Here are two more matches from Barksdale site 9/22/12, both broken in antiquity
Nacho's find..
The missing piece never showed up
Elaine found the base segment, the sliver of tip & edge was on SH's table.
