I have a suspicion that this pattern is from Schneider's 'Vercais' range, though cannot be certain at this point. Most Vercais pieces are signed with an acid stamp or possibly sandblasted mark , though often it is very faint.
Larger pictures showing the pattern detail and base would help.
By the way, the polished pontil by no means means mould blown rather than pressed. it is perfectly possible to find press moulded glass which has been pontilled to support the glass when fire polishing or shaping the rim & I have a number of pieces (mainly ale glasses) which show a combination of press moulding with a ground pontil mark, though I admit the combination is somewhat unusual.
In this case, however, if it is Vercais, it will most likely have been mould blown.
