Blue Glass Jug / Pitcher

I found this yesterday. It needed a reall good clean up and has quite a few hairline scratches but still looks nice. The annoying thing for me is that earlier this week I know I was staring at some photos showing a range of jugs similar to this -- of course now I cannot find those photos. I have looked through my books so the pics I was looking at must have been online. Hope someone can help please.

The jug is approximately 7" high and weighs in at about 670g. There are no marks on the bottom. It is very slightly wobbly.
