I have an 1860 Army with serial number 1011XX, also manufactured in 1863. It has the same two cartouche inspectors as yours. I don't know if there is any way to find out who the individual soldier was that it was issued to. Information that I obtained from Pate's 1860 book was that mine may have been in a shipment of 1000 guns to the New York Arsenal in May, 1863. Another member might have better information. BTW, I like the look of yours.
