[meteorite-list] AD/Trade Books: looking for O'Keefe(1976) swap for Mason or Burke?

[Phil Morgan]

I'm looking for a copy of O'keefe's 1976 Tektites and Their Origin 
(Developments in Petrology) and wondered if by any chance anyone would 
entertain a copy of Cosmic Debris (Burke) or Meteorites (Mason) in trade. 
Both are ex-library hardback.

Please respond off-list.

Thanks and Regards,
Phil
