To Ekimp:
It's difficult. It's very hard to compare canes off a screen or picture. The way they've been cased in clear or if they've not been cased in clear, how they've been laid on to the piece etc. It's really hard to compare and errors of judgement can be made without having them both in hand.
The size of the base of the piece should not make it difficult to do a large polished pontil mark almost to the edge. I have a cameo piece, tiny, that is in debate/research (was told probably Bohemian but I think it's definitely French) that has a large polished pontil mark right to the edge and it's very small. Probably 2.5cm diameter or less on the base.
This picture of my little cameo piece shows the green overlay showing through the base in speckles - so
isn't the best to demonstrate that, despite the snapped off little mark in the middle still showing,
it has a large concave polished pontil mark almost right to the edge of the base. It's a tiny piece 9cm tall with a tiny footed base:
