This is really interesting. Could you tell us where you read this as I never noticed shot lockers near the foremast. This makes sense but where would it go? There is the light room, filling room and magazine taking up that entire area.Hi, from what I’ve read, the 2 shot lockers were around the main and fore masts
Brian Lavery describes the shot lockers, magazines, and filling rooms in The Arming and Fitting English Ships of War. He writes that in addition to the two at the main mast, by the middle of the 18th century there was sometimes a shot locker aft of the main magazine. This would put it pretty far aft of the foremast which typically passed through the light room on medium and large ships.
Then again there were variations all the time so perhaps Victory was an anomaly.
