[meteorite-list] Is there a Main Mass list?

[Jeff Grossman]

  A main mass list? Heck, there isn't even a "main mass" definition 
everybody agrees on! Here's mine:

"An individual stone/iron or piece of an individual stone/iron that 
comprises the majority (> 50%) of the known mass of a named meteorite."
