1840 (Aug) Southgate no.3 envelope from Moffatt to Lockerbie bearing 1840 1d black pl.6 JJ placed centrally, with good to very large margins showing a portion of the adjoining stamp at foot, neatly cancelled by a very fine strike of the red Maltese cross (not tied); the cover with some toning not affecting the adhesive, a superb and very rare usage, cert. RPS (1974) stating “Genuine as far as one can say”.
