Military bayonet with wooden checkered grip

This item is a historical edged weapon, specifically appearing to be a military bayonet featuring a single-edged steel blade, a metal crossguard, and an integrated hand guard or knuckle bow extending from the pommel to the crossguard. The handle is constructed from wood with a distinct diamond checkered or diamond-point pattern providing grip texture, and it includes a metal locking mechanism release lever along the spine of the grip. The overall physical condition displays heavy age-related wear, oxidation, pitting, and rusting across the exposed steel blade and metal fittings, consistent with a military surplus artifact of considerable age. The wooden grip shows minor surface wear, discoloration, and patina. Regarding markings, the user notes that the item has the number '65598' on it, though this owner-supplied information remains unverified and requires physical inspection. The item style and construction details are consistent with late 19th-century or early 20th-century military sidearms, often associated with various international infantry rifles of that era, though no definitive maker's mark is clearly legible in the current view to confirm a specific country of origin or model. The identification of this piece is based purely on visible morphological characteristics such as the checkered wooden grips, curved guard, and blade geometry, with all attributions and specific details remaining unauthenticated.

Based on what I can see in the provided photographs, this item appears to be a historical military bayonet featuring a single-edged steel blade, a metal crossguard, an integrated knuckle bow, and a wooden grip with a diamond-point checkering pattern. Per user submission, the item bears the number '65598', though I cannot verify this marking from the current images alone. I can't verify the exact model, country of origin, or period of manufacture from a photo. The physical condition displays heavy age-related wear, oxidation, pitting, and rusting across the steel blade and metal fittings, while the wooden grip shows minor surface wear and patina. Assuming the working hypothesis that this is a late 19th- or early 20th-century military sidearm, comparable surplus edged weapons in similar weathered condition typically trade in the $150 to $250 range within the collector market, driven by general interest in militaria rather than specific verified provenance. If physical inspection reveals the piece to be a modern replica, theatrical prop, or a later copy 'in the style of' the period, the market value would drop significantly, likely to the $30-$60 range. To establish a more precise evaluation and assess authenticity, a physical inspection by a qualified militaria expert would be required to examine the metallurgy, construction techniques, and any faint maker's marks or serial numbers obscured by corrosion.
