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 ServiceNo P/22170 against this record's 52640. The two numbers are unrelated, not a transcription slip. Either this record's number is wrong, or Mike's entry belongs to a different man who shares the surname and date of death. Not resolved. Flagged, not changed.
16 Sep 2026, ServiceNo contamination sweep: the stored ServiceNo '52640' was CLEARED. It was not a reading of this man's record. PersonNumbers 41629 to 41633 -- 5 consecutive records -- all carried the identical number, which belongs to the record at the head of that run (41629, Van Staden, Marthinus Hermanus Johannes (M H J)). 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.
