Just under 14,500 Merrill carbines were manufactured in two variations during the Civil War. This is the second type with slightly different stock contours, no patch box, and the button type latch. Merrill carbines were almost exclusively issued to cavalry units during the war, including units from New York, Pennsylvania, New Jersey, Indiana, Wisconsin, Kentucky, and Delaware. The lock is dated "1864." "T.K.L." inspector initials stamped on top of breech. The left stock flat has two faint boxed script inspection cartouches.

Very good, with gray patina and scattered areas of light pitting on the crisp iron surfaces, defined lock markings, and bright patina on the brass fittings. The re-oiled stock is also very good, with a few light scratches and minor filled in repairs visible, and lightly visible cartouches. Mechanically excellent.
