The location of the OB is unknown. The centre of Dorchester has a number of tunnels and chambers beneath buildings. There is even a tunnel leading from the Prison (now closed) though this is not thought to have been used by the Auxiliary Unit
Dorchester (Prison) Patrol
Most of the Patrol appear to have worked in the Prison.
Cross and Marshall are most likely members of this Patrol, rather than other in the West Dorchester area, based on their occupation. Lynn (see unallocated men - Dorchester) also has Dorchester address, though it is less clear which Patrol he belongs to in this group.
