Michael J. Barrett Miniature Winchester Model 1903 Rifle
This miniature rifle was made by Michael J. Barrett and was donated in memory of Joseph Macewicz.
This miniature Winchester semi-automatic rifle was fired with special ammunition handcrafted for it. Like most miniature arms, the small amount of ammunition crafted for it was quickly expended.
