What made a Basic Field Manual "Restricted"

[Persian Gulf Command]

Whould like to know why some Basic Field Manuals were deemed "Restricted"?

 

For example:

 

Thnaks, - John

[Persian Gulf Command]

Compared to:

[dustin]

All that means was that it was not for non-military or government personnel, eyes. Nor sold or distributed to the public.

How do you know the 2nd one wasnt marked as restricted???

[Persian Gulf Command]

It is a poor photo as the top is croped out but the 2nd one does not have "Restricted" at the top.

Is the second one a reproduction?

 

If so, is it possible "Restricted" was not included in order to make it easier to sell?

Normally first printings during the war were restricted if they introduced new technologies or techniques that were not deemed classified. Subsequent printings at later dates would not be restricted even though they may have the same initial publication date. Normally minor changes are released as changes, however, after numerous changes or a significant change a new publication will be produced and that will get a new publication date. Under normal conditions, not wartime, it takes about 18-24 months to get a publication through staffing and editing before it can be updated and printed unless its a staffing priority, etc.
