The US M1861 contract rifle muskets with the "Windsor Lock" marked locks are attributed to the earliest delivered by William Muir who had a contract to provide 30,000 rifle muskets to the US government. Only the earliest guns bear this lock mark, as later ones are marked with Muir's name. Muir actually fulfilled the contract by delivering the full amount between 1863 and 1864. {ANTIQUE}
