re: French protectorate surcharge on French Morocco stamp
You may have found an error. I saw several Morocco stamps on Auction with one of the several possible o/p missing (the 5c, 10c 15c and 25c missing are noted in Scott). I don't know if this one specifically is noted in specialty catalogs, but it is possibly an error.

re: French protectorate surcharge on French Morocco stamp
I found a reference for the lack of Arabic overprint and it is possible that the stamp also has the "S" variety reversed.
You have the address at the top.
