Scarce US Navy Marked Trapdoor Socket Bayonet & Scabbard USN Span-Am War

This is a US M1873 Trapdoor Socket Bayonet with the original USN marked scabbard and frog.  This standard Trapdoor rifle bayonet was issued for use by sailors in the US Navy housed in arms lockers on ships.  The 18" blade retains 85-90% of the original bluing with "US”  on the ricasso, the blade has a shows light freckling and some nicks along the edges. The tip is excellent with no deviation.  The 3 inch socket shows perhaps half of the original finish with some surface roughness and non-discernible lightly inscribed writing.  The steel scabbard is mostly plum brown with a very small dent about four inches from the bottom on the back side with a slight separation on the top inside edge.  The leather frog shows “C H” inspector marks with on the back and has good stitching with crazed surface but overall supple leather.  A nice and very scarce US Navy bayonet that would add to a Trapdoor collection.
