Nice one! I think I'm right in saying you can still visit the remains of the wartime Ardeer munitions factory down at the shore, though there's increasingly less to see these days.
Next time you're across Stirling way, try and visit Bandeath industrial estate at Throsk. This was a Royal Navy Armaments Depot until 1978, but dates from pre-war.

There's a book called
Dangerous Energy by Wayne D. Cocroft which charts the story of gunpowder & explosives manufacture in the UK from the 16th Century until the 1990s. It gives a pretty good background to all the factories from both world wars.
You can probably get it second-hand from
