Hi, welcome to the forum. Made in Egypt, assay office Cairo, silver fines 800/1000, the lotus flower of 1946-2005, ح (ha) year letter used May 1946- till July 1947.
Hi, Egypt, Cairo, fineness 800, lotus flower national mark, date letter in Arabic used 1947, possibly repeated later. See here under Egypt section: https://www.925-1000.com/foreign_marks2.html Regards
Date letter repeated 1996, more probably the year the box was made (having in mind the situation in Middle East I doubt there were many tourists in 1947).
The first mark is a combination of the assay office (the mark at the top), which in this case is Cairo, and the silver content expressed in Arabic numerals: ۸۰۰ is 800.
