Zululand 1888 ½d GB9 Somerset House Specimen

1888-93 ½d vermilion (SG 1). F/M part OG example HANDSTAMPED SPECIMEN TYPE GB9. The GB9 handstamp was primarily applied to stamps retained as specimens in the Inland Revenue reference collection at Somerset House. Infrequently the GB9 handstamp was also used to cancel specimens of overprinted GB postal issues supplied for UPU distribution. This practise was discontinued after a short period of time in favour of more permanent defacements.
