Hi Shawn '
It is interesting, after a few years I collect some of them, I do not known what they are, but they have some different shape some times and some variability of the size too...
It was thought interesting, so I collected a couple, I was hoping someday turn out to be what they are and what they were used at the time. I really think the
Roman era.
I will post some others if I turning
home ..
Best regards
