Bayonets

German M1871 brass-handled bayonet modified into a trench/fighting knife; appears to be a period conversion.
Hilt grip is solid cast-brass, steel cross-guard and attaching mechanism.
Overall length is ~11-7/8"; blade length is ~6-3/4".
Fair to good condition considering the alterations. Blade has been shortened, upper and lower quillons (swept portions) removed, muzzle-ring remains intact.
NOTE: No scabbard.

Italian Model 1891 Carcano Rifle Bayonet without scabbard. Bayonet has apparently been sand-blasted smooth to remove rust, so some restoration is required (see images).
Overall length is ~16-3/8"; blade length is ~11-7/8" by ~15/16" wide by ~1/4" thick (at ricasso). Blade feels unsharpened; single fuller both sides.
Wood grips; steel pommel and crossguard (stamped with what appears to be RD375).
NOTE: No scabbard.
Fair condition overall.

Original Prussian Model 1809 "Potsdam" Musket Bayonet for the 1809 "Potsdam" Flintlock Musket .71 caliber and the 1809/1839 percussion conversion muskets. Prussia began large-scale conversion of the M1809 from flintlock to percussion circa 1839, becoming the M1809/39, but research indicates conversions may have started as early as 1831. The name "Potsdam" comes from the guns made at the Prussian Potsdam arsenal.
These weapons saw service during the Napoleonic Wars and many of these were acquired during the American Civil War and were used by both sides during that conflict; this would also be considered correct for revolutionary Texas. This bayonet was found in Aransas Pass, Texas where Confederates were garrisoned during the Civil War.
Overall length is ~22-3.8"; blade length is ~19".
Relic condition as it has obviously seen the salty climate of Aransas Pass.

Remington long socket bayonet for any number of Rolling Block rifles, domestic and foreign. Unmarked.
Overall length is ~24-1/2"; muzzle length is ~2-7/8", shank length is ~1"; Z-mortise slot with attaching ring. Triangular blade length is ~21-1/2"; blade has deep un-stopped fullers on the sides - without shoulders - and shallow stopped fuller on the face; blade face at ricasso is ~3/4" wide.
Overall condition is about fair to good with scattered pitting (see images).

Romanian AKM Type I Knife Bayonet with scabbard only (no insulator or scabbard belt hanger). These were introduced with the various AKM "stamped receiver" AK models originally introduced by the Soviets in 1959.
Wire-cutter style using the bayonet and scabbard as a pincer/plier-type cutter when connected together via a pivot point at the scabbard drag (tip). Bowie-style, clipped-point blade.
Overall length in scabbard is ~13-1/4"; overall length out of scabbard is ~11"; blade length is ~6". Reddish-brown composition grip.
Matching serial numbers.

Overall conditions about good.
