I have had a look at your photo album, in the Chippendale album no 28 a large water jug, cannot find it in catalogue.
Bagley made a water set in a patten called Queens Choice which is very much like Chippendale, it is in Angela's book on Bagley Glass, has your jug a Reg No inside on the base, 698049 May 1923.
