Further questions, did Thomas Webb ever leave a snapped off pontil mark rather than a polished pontil mark? On another thread I think it was established that they did not always mark their glass. I can find no reference that Stevens and Williams did the same finish as I'm looking for and nor Walsh Walsh - although I think the 'feel' and finish thickness/fine'ness' of Walsh Walsh mother of pearl ( I have some of these) is the same or very similar to what I am looking at. Does anyone have Cyril Manley's Decorative Victorian Glass and would be willing to look something up for me please?
Many thanks
