The listing, Orange River Colony lot of 7 stamps Est CV $23 has ended.
Up for auction or GIN is a very nice lot of stamps from Orange River Colony, which was "the British colony created after Britain first occupied (1900) and then annexed (1902) the independent Orange Free State in the Second Boer War. The colony ceased to exist in 1910, when it was absorbed into the Union of South Africa as Orange Free State Province" (Wikipedia).
