A claimant alleges a DB of 6/10/22, and the file contains:
         
            - 
               
                  • 
                     A school record established 4/15/30 showing age 7,  and  
 
 
- 
               
                  • 
                     A NUMIDENT indicating an SS-5 established in 1939 showing 3/10/ 22. 
 
 
It would clearly be erroneous to establish 3/10/22 as the DB, since the school record
            would indicate that the claimant was born during the period 4/ 16/22 to 4/15/23 inclusive.
            To find a DB outside of this period would be incorrect on the basis of the evidence
            in file. (In such cases, secure additional evidence as to month of birth.)
