There is a note on page 1930 of the 5th Edition AAMC (American Airmail Society Catalogue). Bottom-line: if the cover you must have a Sweden receiving cancel backstamp between the dates of April 4th to 7th, 1946 to be a genuine first flight cover; otherwise this is not a true First Flight.

You might find this link interesting. As noted in the previous post, specifically checkout F24-13b:
