Taken at New Windsor Cantonment in May, 2015.
The Cantonment contains a working forge and part of the tour included a demonstration of how to make a nail using the tools and other equipment available during the Revolutionary War. A single guide took us around the site, explained the history of the camp, did the musketry demonstration (i.e. he showed us how to load, and fire a musket), and also did the blacksmithing.
This picture above shows the tools in use at the time.
