Nyasaland 1935 Silver Jubilee complete set of 4 to 1s, perforated 'SPECIMEN' (type W8), SG123s/6s.
A brilliant mint set with original gum. The 2d stamp has a few shortish perforations, but doesn't detract from such a fine 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 £140.
