I noticed I have the two types for Cundinamarca #15 and I thought I should share them here.
Type I, though, is cancelled so details are a bit hard to see:
Main clues are: - V shape above RCA in top CUNDINAMARCA points up, instead of down (so looks like ^ instead of V). Compare it with the V shape above first C of the same word. - No period after COLOMBIA - Period after PROVISIONAL - Second 8 in 1883 is slightly larger
Type II looks better here:
Main clues are: - both V shapes above top CUNDINAMARCA points down. - Comma after PROVISIONAL - Small S in center CORREOs - Sometimes the top right corner of the frame is damaged.
The fakes, based on Dieter Bordfelt, show a larger 3 in 1883, the two 1s in the bottom are different than the genuine design, shows a larger weird L in PROVISIONAL.
