Some postage due items from Taunton starting with a postcard that was underfranked in 1950. The Postcard Rate was 2d not 1d.
The envelope below was unfranked and received a green Posted Unpaid cachet in Manchester in 1959, with the postage dues being cancelled in Taunton with oval Registered cancels.
The unfranked postcard (a registration for guarantee for a "Tidyspin Deluxe") was refused in Birmingham in March 1971 so the sender had to pay.The windowed envelope below had an incomplete meter mark in November 1975 so was liable to postage due. The green cachet applied was an old one, still referring to old pence ("D").
The postage stamp on the envelope below had been fixed with adhesive tape in April 1978, and was marked as "Stamp Defaced".
And finally an example of the post office being over keen in 1987 and charging postage due on an unfranked envelope that was addressed to a Freepost address - the postage due stamps were "Cancelled".
