My Scott catalogue lists the 1921 postage due (J86) as 25k on 1.5k violet. While the original (unsurcharged stamp, Sc# 342) is listed as brown violet. Then when I look on stampworld they list one variety as brownish purple. Knowing that Scott often does a superficial job at covering foreign stamps, does SG or Michel list two different color varieties?
Thanks for any insight you can provide.
