Well, I spent some time yesterday photographing my dressing table jars and looking up hallmarks, so I hope this helps, Tabatha.
And thank you Anne, I have at last ditched tinypic and ventured to use yobunny!

Aren't I brave? :roll: :lol:
This hobnail pattern one (7.5 x 6.5 cm) has a very 'nouveau' image of flowers - poppies, I think - on the lid. It is dated 1905 by the hallmark.
http://glassgallery.yobunny.org.uk/displayimage.php?pos=-1109 This is pressed glass. You will see that the glass is very 'yellowish'.
This smaller one (3.5 x 3 cm) is dated 1892
http://glassgallery.yobunny.org.uk/displayimage.php?pos=-1110 It is cut glass, much clearer in colour than the previous one. The lid has a 'Green Man' image, with leaves, birds, etc.
Here's another little (4 x 3.5 cm) Green Man jar, this time dated 1893
http://glassgallery.yobunny.org.uk/displayimage.php?pos=-1113 This one is not hobnail. Pressed glass again, but not so yellow as the 1905 jar.
Here's a Green Man bottle (8 x 5 cm). This is a cut hobnail pattern and the hallmark is for 1892 also.
