Well...., I'm a little surprised of your Polish plot Ariel, I didn't think about it that way, at first glance. What do you mean by "modern souvenir"? - if you mean made within last 50-10 years, then I would be sceptical, though I don't know the tourist market very well. I would be surprised if someone wanted to sell as souvenir sabre with Persian marks, until it is one or one of very few examples to cheat someone. What you can buy today are almost only those sabres where you can find strictly Polish inscriptions. But who knows? Anyway the hilt might look Polish, but it could be from anywhere else too. Such hilts, made of silver, often with not high quality engravings are seen in Polish karabelas from the 2nd half of the 19th century. The motif of the little flowers was in use in Polish armament from the ca. beginning of the 18th century, as an influence of Persian art. But all of these doesn't exclude the possibility of other country origin, in my opinion. There are no real Polish features that could tell us for sure it was/is souvenir from this beautiful country. Maybe the blade is misleading me... but I just don't feel the National spirit in this sabre
. Just might be, but nothing for sure.
