Thanks a lot for your impressions, David.
I am actually thinking of visiting the museum, which is actually not far from here; i just hope to find someone there specializing in this specific sort of things. The museum has diverse kinds of archeologic stuff, specially on the stone area, with a large "collection" of primitive swasticas.
Also at this very moment and as adviced, i am posting the pieces in SFI, on the Ancient Weapons section, where the moderator is an expert on Bronze Age casting.
Let's see what comes up.
Thanks for your (allways) enthusiastic support
