Sources & verification

Year and watermark/value combination supported. Exact issue day, shade and overprint setting remain unresolved. The 1964 study distinguishes larger overprint lettering on the 2/-, 2/6, 5/- and 10/- values and explicitly reports red overprints on 2/- and 10/-. This is a denomination-specific overprint description; ink colour is not inferred for the other values.
