Mike Sandham's research log ("List 1"), imported 16 Sep 2026, credited to The South Africa War Graves Project unless his entry says otherwise: gives Age 48 against this record's 55. This record has no date of birth, so there is nothing to adjudicate with. Flagged, not changed.
16 Sep 2026, ServiceNo contamination sweep: the stored ServiceNo '01575786PE' was CLEARED. It was not a reading of this man's record. PersonNumbers 41690 to 41694 -- 5 consecutive records -- all carried the identical number, which belongs to the record at the head of that run (41690, Human, Johannes Petrus (J P)). A value repeated down an unbroken block of PersonNumbers is a forward-fill import artefact, not men who shared a service number; the pattern holds across 850 such runs on this roll and is independently confirmed by Mike Sandham's research log, which attaches such numbers to the head of the run 167 times against 6 contradictions (all examined). No replacement is guessed: this man's real service number is simply not known, and a blank field says so honestly where another man's number did not.
7 Oct 2026: Rank "Sergeant" filled (was blank), per Col (rt) Graham du Toit Last Post, 7 Oct 2026. SAWGP (details.php?id=41694) gives Regiment "Union Defence Forces" and confirms name, date and burial at Thaba Tshwane (Old No.1) Military Cemetery. Date and cause consistent.
