This is an interesting new sea-level diagram from Batchelor et al (2019), based upon a great deal of new research. It's not that different from earlier published curves, and it shows that within the two last glacial episodes (MIS-6 Devensian and MIS-2 Wolstonian) the pattern of global cooling -- and hence of sea-level fall -- was similar, but slower in the case of MIS-6 and faster in the case of MIS-2.
In both glacial episodes sea-level fell to almost -130 m, and recovered to the interglacial level relatively rapidly after the glacial peak, as a result of catastrophic ice wastage in all of the Northern Hemisphere ice sheets.
On another graph the MIS-12 (Anglian) glaciation saw a similar fall, to the same level, with the lowest sea-level experienced around 430,000 years ago -- slightly later than in some other reconstructions.
