I wonder if you could try---providing you haven't already!--contacting a museum in England, which might be more likely to have examples of bottles from British glassworks, particularly the Museum of Tyne & Wear County.
Tyne and Wear County Council Museums
Museum of London
According to an expert on the history of British glass factories, associating bottles with their makers is difficult unless you have a local museum with donated examples. Many were sent to America and probably to India and other parts of the Empire at that time, so they could turn up anywhere.Not much research on the factories dealing with bottles has been done, either.
So it does sound like contacting the Tyne & Wear Museum, as it is local to the Hartley Glassworks, would be a good step. Also, contacting the Seaton Sluice & Old Hartley Local History Society might turn up additional information, if you haven't done so. They also might be more immediately responsive than the Museum of London or other large institutions. Their website is: http://www.seaton-sluice.btck.co.uk/Contact%20us
Several have appeared in our Journal of Glass Studies on British bottles. You might try contacting the author of these, who has done extensive research on British bottles from the time period you are interested in.
