With the Royal Navy's nuclear submarine fleet on their doorstep, it's fair to say the inhabitants of the towns and villages around the Firth of Clyde have been all too aware of the ever-present threat it has posed over the years.
But while HM Naval Base Clyde at Faslane may present a worry to the local population today, previous generations have also fretted over volatile substances being stored within close proximity of their homes.
Just 20 miles southwest of the nuclear sub base is a little settlement called Millhouse, near the shoreside village of Kames on the Kyles of Bute, that for more than 80 years was famous far and wide as a manufacturer of high grade black gunpowder. The Kames Mill, as it was known, was not without its major mishaps.
