[meteorite-list] whats the 1st meteorite from The Nininger Collection of Meteorites?

[Shawn Alan]

Hello Listers

I have a question about the Nininger meteorite collection.
I have seen some of the meteorites with numbers only and some with numbers and letters, why is that....
I am assuming 1a or 1 would be the first meteorite inducted into his collection. Does this
mean that's the first one he owned? Lastly, what was the first meteorite 
put into The Nininger Collection of Meteorites?
