Musket at the Betsy Ross House

Yesterday I chaperoned my daughter's class trip to Philadelphia. Among the places we visited was Betsy Ross's House. In the basement, they have displayed a musket and information on how paper cartridges were made during the Revolution.

The musket is either a French Charleville, as supplied to the Continental Army during the Revolution, or a US M1795, which is nearly a direct copy. This page also has a good description of how paper musket cartridges were made.
