Hi! I stumbled upon your website and was hoping you could help me or perhaps point me in the right direction. I have recently received a M1862 Sharps & Hankins patent naval carbine with the matching serial number of #11,143. I am trying to determine the history of this serial number - when it was produced (month and year if possible) and if there is a record of this gun being issued to a specific regiment or state. Any information you might have, or resource you might know of with such information, would be greatly appreciated! Thank you so much!
