Chamberlain (M A)

Cleared stolen ServiceNo P/50083 (belongs to Chamberlain PN 29719, Shackleton 1718-K 1963-08-08). 1963-01-01 row looks like a placeholder twin.
FirstName contamination fixed 31 Aug 2026 (systemic full-table scan): FirstName ("Johannes") was copied from the unrelated neighbouring record PersonNumber 29719 ("Chamberlain, Johannes", initials J) -- this record's own stored initials (M A) don't match "Johannes" at all. Confirmed by the existing 25 Aug 2026 SN CORRECTION note on this record, which already identified PersonNumber 29719 as the true owner of this record's copied ServiceNo via the same external source. Cleared back to unknown rather than guessed.
4 Sep 2026: Regiment leftover "South African Army" cleared -- that's the service branch (Army, as distinct from Navy/Air Force), not a specific regiment; the actual unit ("35 Squadron") is already captured in Unit. Per John's decision, the 52 records with no better Unit info were left as-is.
