Early version of the Ottoman flag, used during 1793-1844 according to Zanamierowski (1999).

"Zanamierowski [zna99] gives 1793 as the date for the introduction of the red flag with white crescent and star (presumably as some sort of flag for national identity) and 1844 for the change from an eight-pointed to a five-pointed star, (not that I doubt it) but I have never been able to discover any other source to confirm or refute the information?" Christopher Southworth, 18 January 2011 (crwflags.com) This map is made based on that description.
