26 (25) 1888 4d on 4d lilac and black Q Victoria^, wmkd Orb, perf 14, SG Type 6 red surcharge, an exceptional USED rarity, hardly ever offered and considerably more difficult than either a £5 first issue or even a 2d on 2d green surcharge, vastly undercatalogued (as any serious collector who has tried to find one will attest), we have seen only 4 used examples in close to 60 years, canceled at "Zwart Modder" - rare usage from a remote village.
