Just to let you know if you want a piece of Citadel history, I have a spare LE2 or Bolter 5 marine as seen from Stuff of Legends. http://www.solegends.com/citle/citle1990/numbered/le02SpaceMarine.htm
I don't know if it is an actual LE2 the First Space Marine as it was re-released in 1991 catalogue as Bolter 5, same cast, same Marine. I guess only destructive examination metalurgy will know hence the low price.
No obligations, but if you fancy it fellow bloggers, check the sale out here: LE2 or Bolter 5
