One of approximately 20,600 percussion carbines produced by Starr Arms Company of Yonkers, New York circa 1862 to 1865. This carbine is a 54 caliber percussion, single shot with a falling block breech mechanism. The lock is marked "STARR ARMS CO. / YONKERS, N.Y." and the upper tang is marked "STARRS PATENT / SEPT. 14TH 1858" directly behind the hammer. The top of the barrel in front of the rear sight is marked "STARR ARMS CO YOUNKERS N.Y.", with the serial number appearing on the bottom of the barrel under the forearm and locking block. The left side of the breech is marked "HGS" and the left side of the rear sight base is marked with the letter "B". Fixed front and two leaf rear sights, saddle ring and staple mounted on the left rear of receiver, brass single barrel band (marked with a "U" and "B") and buttplate ("W" on tang) and smooth forearm and straight grip stock with no visible markings. In government tests of the Starr carbine, it rated higher than the better known Sharps carbines. The Starr carbine was issued primarily to Union cavalry troops in Arkansas, Kansas, Missouri and New York.

Excellent. The barrel retains 95% original blue finish with some scattered minor spotting and pitting. The receiver, hammer and lock retain 90% plus bright case colors with a smooth gray present on the upper tang. The lever has mostly turned a smooth silver gray patina. The buttplate has an even aged patina. The wood is very fine with a few pressure dents on the left side of the forearm and overall, a few minor dents and dings. The markings remain clear. The mechanics are excellent.
