Peverelli , Sylvester Lewis (S L)

Data correction 23 Aug 2026: Unit2 previously read "attd. 61 Mechanised Battalion Group", flagged by John Dovey as chronologically impossible since 61 Mechanised Battalion Group was not formed until 1978/1979, well after this person's death. Cross-checked against the 61 Mech Veterans Association official Roll of Honour (61mech.org.za/index.php/roll-of-honour) and found no matching entry on either roll tab. Value cleared as a data-entry error; primary Unit/UnitID left as recorded. SN CORRECTION 25 Aug 2026 (year-prefix method): ServiceNo 78397122BG cleared -- per the documented SA force-number convention (data/SA_SERVICE_NUMBER_NOTES.md), the prefix '78' implies registration circa 1978 (usually age 16), i.e. birth circa 1962. This record's own Age/DateDeath implies birth circa 1908, a mismatch; PersonNumber 32478 (Pettit, implied birth circa 1962) fits instead. Original value: "78397122BG".
