There were a few 12 pdr artillery guns on both sides of the Brandywine river. They are bigger pieces than other present but after looking at the plastic market... nothing.
So once again some improvisation was required.
The Revell 30 YW artillery set has some large caliber guns which seem very close to XVIII century ones. Only the wheels are too small.
So some ESCI and Revell Napoleonic wheels were pressed into servive and here they are looking pretty close to the 12 pdr used in the American War of Independence by both sides. As Service Ration Distribution once pointed out, if you use new wheels on old carriages everything becomes more lively as he did with the old Airfix French artillery.
After painting they look the part.
