On the left is the cross-sectional model of a Finnish "munakasikranaatti 32 sirpale," which translates to "egg hand grenade 32 fragmentation." This hand grenade was made from the grenade bodies of a 47mm mortar grenade, with the tail and fuse removed. The hole for the tail was then covered with a brass screw, and the fuse was replaced with the M32 grenade fuse. Two types of mortar grenade bodies were available for this grenade: the "pisara" (teardrop) and the "soikea" (oval); far fewer of the oval type were made and are from pre-war production. The version depicted here is the oval. The grenade body is made of gray cast iron.
Weight: 600 grams.
Total length (with fuse): 138 mm.
Grenade body length (without base screw and fuse): 90 mm. Diameter: 46.5 mm.
Explosive weight: 60 grams of TNT.
Effective radius: 15 meters
On the right the cutaway model of the Finnish "munakäsikranaatti 43 sirpalevaikutteinen," which translates to "egg hand grenade 43 fragmentation." The grenade body and lid are both cast from gray cast iron. Unique to this hand grenade is that the lid, which houses the detonator, is not attached to the grenade body by a screw connection, but by a copper wire and cast lugs on both the grenade body and lid. This conserves scarce production resources and production capacity; besides casting, virtually no mechanical work is required on the grenade body, except for the threaded hole for the M32 grenade fuze. Besides this M43 version, there is also the M41 version of the grenade. The difference lies in the number of lugs on the grenade body and lid; the M41 has six –smaller- lugs on the grenade body and lid, while the M43 has only four.
Weight: 560 grams. Total length (with fuze) : 137 mm.
Grenade body length: 93 mm.
Diameter: 45mm.
Explosive weight: 60 grams of TNT.
Effective radius : 15 meters
The M32 hand grenade fuse (photo 3) is an all-brass fuse with a percussion primer and a pyrotechnic delay. To throw the grenade, the split pin on the ring (1) is pulled out of the brass cap (2), after which the cap is pulled off the fuse. Then, the clip (3) around the axis of the firing pin is pulled away from the link. The firing pin is now released, except for a thin iron break wire (4) that is inserted through the firing pin and the firing pin housing. The fuze is then struck with the brass button (5) at the top against a hard object to drive the firing pin into the primer and ignite the pyrotechnic fuse. Four holes are drilled around the primer to release the gas pressure from the burning fuse. After 5 to 6 seconds, the fuse ignites the detonator, and the hand grenade explodes. It is wise to throw the hand grenade in the enemy's direction beforehand.
Fuze weight: 70 grams.
Fuze length: 109 mm
