Inert Mk 2 Fragmentation Hand Grenade

This item is an inert replica or a deactivated example of the classic United States Mk 2 fragmentation hand grenade, colloquially known as the 'pineapple' grenade due to its characteristic segmented exterior. The body is constructed from cast iron with a dark, possibly black or deep olive drab finish, featuring the iconic cross-hatched serrations designed to facilitate fragmentation upon detonation. The fuse assembly is attached to the top, including a lever (safety lever or 'spoon') and a visible striker housing. Based on its appearance on a domestic carpet, it is likely a training aid, paperweight, or military collectible. The surface shows a slightly matte, textured finish consistent with cast metal. While no specific maker's marks are visible in the low-resolution image, these items often feature stamps on the fuse or body denoting the lot number or manufacturer. The condition appears stable with minor surface wear, typical for a display piece or surplus item. It represents a design used extensively from World War II through the Vietnam War era.

Based on my visual examination of the Mk 2 'pineapple' grenade, I have assessed it as a surplus inert training aid or modern reproduction. The cast iron body displays the standard 40-segment fragmentation pattern common to the WW2-era design. The matte finish and high-profile casting seams suggest this is a common 'hollow-body' inert variant rather than a live ordnance piece that has been professionally deactivated (EOD cleared). The fuse assembly appears to be a standard M228 or similar practice fuse, indicated by the safety lever tension and striker housing condition. Market conditions for inert Mk 2 grenades are stable due to high supply and consistent demand among military history hobbyists and reenactors. Comparables for common training grenades typically fall within the $40 to $90 range. Higher valuations ($150+) are reserved for verified pre-1945 production with original yellow band 'HE' markings or specific manufacturer stamps (e.g., 'AF' for American Radiator & Standard Sanitary). Limitations: This appraisal is based solely on visual inspection. A physical examination is required to verify the interior of the casting (to ensure it is truly empty/inert), check for specific manufacturer stamps on the fuse and body, and determine if the striker assembly is functional or a dummy plug. Without provenance or detailed stamping documentation, I cannot categorize this as an authentic WWII relic; it is currently appraised as a collectible military accessory. Full authentication would require verifying the threaded fuse pitch and metallurgical analysis of the cast iron to distinguish mid-century production from modern replicas.
