Summarised from report:

Expense magazine no 2 is one of the two original magazines which were constructed at the Drop Battery shortly after 1853. It is a small building of yellow stock brick approached along an L-shaped passage in the rear scarp of the battery. It fell out of use, along with the rest of the battery, in 1886 when the battery was disarmed. The outer arm of the L is ramped down to the profile of the rear scarp, reaching a maximum height of 3.5m, while the inner arm forms a tiny forecourt to the magazine. The doorway to the magazine is 1.98m high and 0.87m wide, with a shallow segmental arch of two header courses and rebated internally for double, inward-opening wooden doors. The rectangular magazine, 2.8m long and 1.45m wide, has an axial semi-circular vault, 2.2m high, coursed entirely with stretchers. The floor has gone but comprised timber boards laid axially on the surviving cross-axial dwarf walls, to allow ventilation under. (1)
