I have added the form for you to download here:http://www.victorianforts.co.uk/docs/ArmyFormG949.pdf
The Victorian instructions were to paste the forms on plyboard and then lacquer (varnish) them.
Drill a hole and hang on a string at the entrance to the shifting lobby.
I have also included prepared forms
Army Form G854 Cartridge and Gunpowder record
Army Form G855 Shell Store
Army Form G856 Fuze and tube record
with details suitable for Drop Redoubt.
These can hung in the Shell and Cartridge stores.
The Fuze and tube Record goes inside the shell store.
Same way of displaying.
Fort Nelson at Portsmouth, Needles Old Battery on the Isle of wight and Valetta Saluting battery at Malta have all displayed forms like this that I have supplied and the varnish seems to work.
