Ancient Manuscript Review 127 : Antique Ottoman Era Document / Letter dated 1249 AH ( 1833 CE )

This is a document written in old Turkish. The document was originally folded and sealed. I couldn't figure out what type of document this is. It could be a legal document or a personal ones. It is dated 1249 AH ( 1833 CE) and the content written in Riqaah script in black. There is a name written Abdullah Efendi on the top of this document whom I believe is the addressee whereas at the bottom there is a signature of Muhammad Musa whom I believe is the writer of this document.
I don't have much information of this kind of manuscript and its writing tradition. I need to do more research on this manuscript and will update this entry later. I welcome any feedback on this letter.
