THIRD SWORD.
Old Omani Battle Sword; Sayf.(half hilt missing) This sword raises a few questions viz;
1. European
PDKG and asterisks ~An unknown Insignia on this blade.
2. Thin and narrow blade.
I would caution that this thinness and narrow aspect of blade is perhaps the only one like this I have seen. I have never before seen this insignia . It may be the missing link ie the so called 17th century european blade for the Old Omani Battle Sword. Note also that the capital letters appear as quite old gothic in style with flared ends as in the first sword at top of picture and in earlier post ( gothic revival ?)

:cool
On research I note a few leads pointing to possible answers from Sotheby's -
1.A small-sword, late 18th century, with hollow-triangular blade etched and gilt with ... circa 1650, with slender double-edged blade, stamped 'Sahagon' within the ... cut with running wolf mark, the spurious date 1616, and the letters
'PDKG' on ...
2.An Indian sword (pata), 18th century, the letters
'PDKG' on ...etc etc
