Here are some photos of from my 'unattributed manufacturer' reference files of a similar creamer in opalescent non-uranium pale green glass. (Permission to re-use these images on the GMB granted by munchandcrunch)
The creamer looks late 18th century in style, and the opalescent green colour is similar that seen in some Sowerby pieces from the late 1870s, but you creamer doesn't match any of the known Sowerby shapes and that opalescent pink is not a typical Sowerby colour.
