Sources & verification

Value and watermark combination corroborated by Spink’s physical collection descriptions. Exact release day remains unverified. 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.
