Hi Just_fella,

The first one is a 2 paras revenue stamp for the tax on Newspapers and Advertisements.

It was standard practice to apply the stamp and then print the document on top of it.

In this case the printing appears to be in Armenian.

The second stamp is a 10 paras proportional fee revenue which has been overprinted for use as a receipts revenue stamp.

The last stamp is another 10 paras proportional fees revenue stamp but this time from the previous reign.

Here the toughra (signature) is of Sultan Abdul Aziz.

The toughra in the second stamp is of Sultan Abdul Hamid II.
