Robbins & Lawrence Armory

The use of interchangeable parts was perfected at the Robbins & Lawrence Armory.

Windsor, Vermont

The American Precision Museum in Windsor, Vermont houses perhaps the most significant collection of historic machine tools in the country. The historic Robbins & Lawrence Armory is the spot where the development of precision metal and wood cutting machines led to the creation of a new type of manufacturing, known as the American System. The 1842 armory building is itself an outstanding example of mid-19th-century New England mill architecture and was designated a national historic landmark in 1972. A Save America’s Treasures grant provided a new slate roof and restorated 60 of the building's 166 historic wood windows. This ensured the protection of the building and the collection inside.
