Hi Sue,
Couple of new pictures of the signature attached. One of the shots is clearer, however the other still has the reflection, although I managed to move the reflection away from the beginning of the signature. Hope this helps, if you need any other shots just let me know and I'll try a few others.
I've seen a handful of earlier chalices around for sale, although not online and they have been on the expensive side of expensive! - They do seem to have become rather thin on the ground.
Thanks,
Greg
