Handsome Set Of 2 Model Desk Naval Cannons

A large Pair of Model Desk Cannons In The Form Of 18th or early 19th Century Ships Guns On Wooden Wheeled Trunnions Weighing in at over 3kg each, this model pair of ships guns are certainly larger than many others that I've seen. Made of either brass or bronze with a nice aged patina they are sited on what looks like oak wheeled carriages. They are completely unmarked, so I am not sure of the size of cannon they are representing, but with my very limited knowledge I would say 18-24 pounders? Overall a very good quality pair of model Navy guns. Barrel (overall length) 33cm, Carriage 19.5cm
