Here are the last stamps I have to show.
These are more of the Alexandria thimble postmarks which are favourites of mine.
ALEXANDRIEN: Alexandria (x3):

I've skipped over the various postmarks of Constantinople and also the later stamps used in the three post offices in Crete (CANEA, CANDIA and RETTIMO) as I need to spend more time to sort out what I have.
Can anyone recommend any other references on these stamps and/or their postmarks? My main concern is with forged postmarks and I assume there are quite a few amongst the stamps I've shown here.
We've seen here how the GÖREAU postmarks are bogus but forged postmarks from real post offices are a much bigger problem.
If anyone can share information on how to identify faked/genuine postmarks on these stamps I'd be delighted to learn from it whether this relates to the examples I've shown or not.
Thanks again Michael for creating this thread. I look forward to seeing how it develops.
