Star marked receiver. Most experts believe the star marking indicates a reclaimed model receiver, which could be correct, as in this example the receiver falls into the late 1879 serial number range but it was produced with many of the 1884 pattern changes before the actual Model 1884 was adopted. The new features include wider receiver, color casehardened high arch breech block with "U.S./MODEL 1873", 3-click tumbler and Model 1884 Buffington rear sight correctly marked with a letter "C". The lock plate still retains the old style "U.S. SPRINGFIELD/1973". The barrel has the "V/P/Eagle Head/P" proofs with no letter "A" on top of the barrel which may have indicated it was an altered configuration, which it is not. Correct carbine style stock with the butt trap compartment, 3-piece cleaning rod and ruptured shell extractor, original sling bar and ring and stamped with a boxed "SWP/1882" cartouche and circled "P" proof.
