You may have examples of 'instructional markings', which were intended to be struck on cover and not the stamps.
PD : Paid to Destination. Another variation can be PP (Porte Paye) : Postage Paid. These can found in circular/rectangular/rounded square frames; and not always in red ink.
I'm sure there are others have far better knowledge of these than I.
Thank you for that suggestion it may give me a new area to research,I am sure one shows a red PD within a small circle
Others are a mystery.

As far as the original question goes, these PP/PD marks were used on foreign mail to show that it was appropriately prepaid. They were struck anywhere convenient on the cover so it's not uncommon for them to have overlapped a stamp by chance.
After much research have not been able to locate information on these reds cancels/marks on the 2d Blues, any ideas?
