Getting there, Max, Mtarfa. I have a small collection of this design - I'd originally mistaken it for Mdina back in 2000, I suspect it might be quite early Mtarfa, as so many of the shapes are quite "Mdina-based", and Mtarfa took off in it's own artistic direction soon after it got going, (which was in 1981) as far as I can make out.
This looks like it was a big bit!
I'm never sure when I see the rough ground neck of something like that whether it came from the maker like that, or met with an accident and got ground down a bit. I've seen a few bits of Mdina like that - but at times when it wasn't popular enough to bother going to that sort of trouble over, not for selling in the secondary market. :spls:
