Can anyone help here. Looks like type 3 to me, but not sure. Cancellation appears to be for a British ship as the cancellation (Port Said) is in English). I ran StampCompare software on this stamp against a known real 5c stamp, my stamp is an exact duplicate, aside from the tiny dots and other things that define the type.
I just don't know for sure as I have read that there are many forgeries. If my stamp is a forgery, it is virtually perfectly done based on computer analysis.
Can anyone provide some insights or precise analysis which could help?
