6 rekords ta’ bolli · ½d / 1d / 1½d / 2d / 3d / 4d

Basic postage-due denomination/design types and documented major paper, watermark or perforation changes. Shade-only printings, plate flaws, errors, tête-bêche arrangements, multiples and unchanged reprints are excluded. Independent specialist verification remains open.

Noti tar-riċerka: Five values (½d,1d,1½d,3d,4d) are attributed to 5 November 1953; the 2d to 20 March 1957. The study classifies sideways watermark type 4. Later 1957,1961,1962 and1963 printings differentiated only by shade are excluded from this bounded physical-type inventory. Printer attribution is supported by the contemporary Said account (printed p16), which identifies Bradbury Wilkinson as printers of these permanent dues since1925. This is a historical attribution; original production invoices and physical printing-process confirmation remain open.
