Hi, all of my angular vases have polished rims,although I have seen examples with a gound rim,including the larger,earlier Lemington Floor vases which I understand were the inspiration for these smaller angulars(around 6 1/2" tall).The bases do vary on mine,most have a smooth polished pontil mark,however I have two examples with a rather unfinished pontil that is still quite rough,as if it has been just partly finished,these two do not have any etched marks.The one I have with a smooth flat base,in a deep cranberry and is also unmarked(and is much heavier than my others,could be possibly due to the colouring perhaps,as it looks to be no thicker?).As far as I can tell,the rim finish and pontil finishing is not indicative of any particular factory,but the floor vases,which were thinner walled, were only produced at the Lemington glass works.
As any catalogues are hard to find,I find that it is very difficult to determine which factory produced which RSW pieces,of course some do have etched marks or labels,but many do not,and personally I do not believe this is a reliable way to decide on which factory produced it,it is often stated on ebay that unmarked pieces are from the Kings Lynn works,but I do not think this is always the case!.
Chris.
PS.I really hope to get our website finished sooner than later,hopefully we will be able to provide an almost comprehensive list of RSW pieces,which should help with ID.(
