This cover appears to be an Apollo 14 Primary Recovery Ship cover from the USS New Orleans. However note the following.

1) The word Atlantic in the top left corner of the cachet should be Pacific. I have never seen this variation.
2) The cover has a second uncommon red postmark of USS New Orleans New York

Does anybody have information on either of these two points. Please email responses to rjsmith@magna.com.au .
