It is a salt and it is meant to be London 1768. It is 6" x 7.75" x 3". I think that stylistically it is not correct for the period but i'm not sure.
Also, the hallmarks don't seem right. I can't find any record of the maker (G J.) or (G I.) and the shields on the marks are square with clipped corners. They don't have the dip at the center of the bottom edge as i think they should.
Could it be Indian/Chinese/british provincial? Maybe Chester without the town mark? or Bristol?
Or perhaps it is put together?

Thanks for any help you can provide
