I NEVER SAW A DATE FORMATTED LIKE ON THAT KHANJAR...
It appears from right to left but in arabic numerals 88 / 11 / 19
with the word hijri
in old arabic...certainly old omani arabic... It cannot be late 20th century since the wear on it is much older than that ... I suspect 19thC. Now could the date be one of those puzzles with numbers... 19 minus 11 is 8 , 8x 11 = 88... It happens to be a day after national day ..Coincidence?... Could it be the date of the placement of a new hilt... ? It is, after all, inscribed on the hilt..which may well be a later addition, We may never know... Any ideas?
