I have multiple examples of the stamps in this set and the only ones I have with perforations is the 40.
All of my perforated 40s are forgeries. The forgeries paper resembles aged glassine for all values of this set. There are numerous design differences as well. The 20 and 30 are described in some detail in Tyler's Focus on Forgeries.
