Sure, you can identify this bayonet !
within the Bayonets and trench knives of the world forums.
All related to the trench edged weapons
Something Austro-Hungarian but exactly what?
Very interesting photographs.
The bayonet is an Ersatz model - for the M1895 Mannlicher perhaps ?
Also made for other captured rifles I think.
Such bayonets were manufactured for the Romanian Mannlicher M1893, the Mexican rifle Mauser M1912, the Italian rifle Mannlicher Carcano 1891, with "Zusatzvisier" upon the muzzle ring for the Repetierstutzen Mannlicher M1895, several designs for the Mannlicher Repetiergewehr M1895, for the Repetiergewehre Mannlicher M1888/90, M1890 and M1890/95, for the rifles Lorenz M1854 and M1862, Extracorps-Gewehre Lorenz M1854 and M1862, the Wänzel M1867 rifle and Extra-Corps-rifle M1867.
Such Ersatzbajonett even was manufactured for the japanese Arisaka M30 (1897) !
Silly me-I didn't notice the lack of conventional grips on the handle-excellent collection of the ersatzen you have there Reibert!
most fakes have the wrong turn (clockwise)
