Ah! Stupid me! In Polish - posolski=poselski

now it's so obvious.Thank you Rivkin!
Hi Brian! This is exactly the same axe! I'm happy about the date, because I'm looking for the axes just from this period (strictly around 1640-50). Thank you for this photo.
If anybody have any other pictures or informations, please post them! I will be happy if you'll find any other examples of such axes from territories on the East of Poland (except Ottoman and Persian ones, these are well known).
Thank you and regards!
