----------------------------Original message---------------------------- Hello, I am trying to find out the projection of a map, and the map librarian here at Oklahoma State University referred me to this list. The map is of Argentina. It is part of the CIA series circa 1971. The scale is 1:7,550,000. The shape of the graticule suggests maybe it's a conical projection, but beyond that I have no idea. If anyone has any information please respond to me at the address below. Thank you for your time.
