In order to find the story behind the cannon, we first need to figure out what type of cannon it is and when it dates to. By measuring key parts of the cannon and taking photos of visible features on the cannon we were able to compare our cannon with others to determine its calibre and likely dates of use.
There are a few key features that helped guide us in identifying the cannon. First, the cannon measures approximately 230cm, or 7½ft, long and the bore (the tube for the cannonball) measures 11cm, or 4.3in, in diameter. Based on these dimensions we can determine that this cannon is likely a 9lb gun - with 9lb referring to the caliber of the cannonballs it would have shot.
