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.)
