AMERICA, circa 1850-60
Depth (Length): 27.5 inches (70cm)
Barrel Length: 26 inches (66cm)
With brass stoppers. On original trunions and mahogany carriages. Complete with quoins/wedges on the bed, and iron tackle rings. Unusually on iron wheels/trunks.
This type of lightweight cannon was probably made for a private yacht although it is conceivable that they were made simply for domestic use.
With thanks to Tony Watts for his help in identifying the origin of the cannon.
