DOM I really love your imagination and commitment it is good
But that tends to complicate things mostly, in the stamp we just have the word سنه (sana)(year) then there is the backwards ی symbolizing Hejri , then from bottom up there is what looks like a / the | that goes through سنه and what looks like the number 8 ۸. Now that latter 3 really just add to confusion and do not make and sense, one can't make any numbers out of them or anything. To me they are just flukes, I went and looked at some other swords of the same with the same stamp and those charactors were not present. The words suggested SHARD شرد (شارد) or SAHD سهد (ساهد( do not make anything. If I find a nice example of these I'll take a pic but for now, let's stop torturing Rick, I think he has alot of good info on the item
Always looking forward to your colorful pics
