It looks very Isle of Wight Studio Glass, to me.
Not exactly sure which range because I can't quite make out the whole thing, but the long streaks combined with the splodges suggests some form of Summer Fruits. (the fruit will depend on the colour)
It's definitely an IoWSG sort of shape, but footed things are scarcer that other shapes.
Again, I'm not exactly sure of the profile shape.
The lack of a mark and the roughly broken pontil mark are becasue it is a footed thing - they ended up getting finished off differently to the more normal ranges.
