Basutoland 1935 Silver Jubilee set of 4, perforated 'SPECIMEN' (type D19), SG11s/14s.
A wonderful fresh set of specimen stamps with original gum. Odd trivial perforation blemishes, immaterial to what is a fine quality set.
These "SPECIMEN" examples were used solely by postal administrations for reference purposes to help spot any attempted forgeries.
The Stanley Gibbons catalogue value is £150.
