Backstory: my dad bought a house in Kentish Town (London) back in the 90s. He found a binder in the loft filled with documents relating to raid procedures that should be followed in a local subway station.

There are over 20 pages dated from July 1939 to August 1939. The documents contain various station worker names and their responsibilities in the event of a raid and essentially documents various procedures to be undertaken. Here are a few excerpts for clarity:

"The Station alarm will bem Six rings on the fire bell"

"Key foreman to see that goods, especially foodstuffs, liable to contamination are covered before the staff take shelter"

All pages are similar to the above.

I don't want them to hide away for another 9 decades, so who should I contact that could shed more light on these? And any specific advice for me when dealing with documents like this?

Thanks.
