Commercial Road, Whitechapel, London E1.
"Proof" is the firing of guns under an over-pressure charge of powder; this determines that they are safe to fire.
The Gunmakers Company of the City of London was established in 1637 by King Charles I, and its role was to promote and regulate the manufacture of guns, a role it still performs today.
