1850 BATHURST to CAPE TOWN: Folded letter wrapper to "C Burton Esq, Master of the Supreme Court, Cape Town" bearing TWO STRIKES of the Bathurst OCTAGONAL 51 handstamp. Most unusual DOUBLY STRUCK thus. F-VF, rare & exceptional exhibition piece. These strikes are from the thin-framed so-called Type 2 implement which we now prove with this strike appearing throughout a discovered find of the re-issued Octagonal in the rectangular period.Click here to view the proving group.
