The title was deliberately shortened; the full version would sound something like " The oldest dated Khyber I can recall"
The date is acid etched on the blade: 229H ( 1229, of course), i.e. 1813 in Gregorian.
The handle was damaged, and the bolster and tangband are made of brass.
Any criticisms or doubts?
The presented etching sample causes me great doubts about the dating of 1813. Very big doubts.
