Following on from this, using the BR Locomotive Database to search by class (for West Country/Battle of Britain) and selecting allocations, it gives a list of all the allocations (since 1948 under BR) for all members of the class:

Taking a couple of now-preserved locos as examples, you can see that 34027 'Taw Valley' had spells at Bricklayers Arms, Ramsgate & Bricklayers Arms again until moving to the Central Division at Brighton (75A) on 26/5/61, while 34070 'Manston' was at Ramsgate, Dover and Ashford (73F) before moving to the Western Division at Exmouth Junction on 9/11/61.
As for the Merchant Navy pacifics, they were almost exclusively used on the Western Division, apart from a relatively short period in the 1950s when a few were allocated to the South Eastern Division, principally to work the London-Dover/Folkestone Boat trains including the 'Golden Arrow', but the Light Pacifics and BR Standard 'Britannia's were more commonly used for these trains.
From BR Locomotive Database -
