German engineering is admittedly often amazing to behold.

But there are also times that German over-engineering will make you scratch your head in disbelief.

The Sprengpatrone had a sweet spot range of about 50 to 150 yards.

With the situation urgent, multiple ideas for man-portable anti-tank weapons came into play.

One of these was yet another step for the Walther flare/grenade-launcher pistol the Sturmpistole (assault pistol).

The Sturmpistole represented another step in the evolution of the German infantrys flare pistol.

In this case, the pistol featured a folding butt stock for stability and clip-on sights to enhance accuracy.

On paper it all looks good the Sturmpistoles weight is only 5.5 lbs.

and its length (with the butt folded) is just 12.

However, its capability as an anti-tank weapon left much to be desired.

Soviet estimates claim it could blast through just 50mm of armor.

To fire this grenade, the user opened the break-action pistol and inserted the propellant charge into the breech.

The break action was then closed and the hammer cocked when ready to fire.

However, many Soviet tanks had particularly thick armor that was also well-sloped.

All the same flares and grenades are said to have been used in this configuration.

Apparently, this was a field modification to approximate the folding-stock Sturmpistole.

Unfortunately, I could locate no photos of this unique grenade launcher.

Examples were captured in Italy and France, and U.S. Technical Intelligence examined them with great interest.

The following report appeared in the March 1943 edition of Tactical and Technical Trends.

The only projectile so far identified is an HE grenade with a direct-action fuse operating on impact.

One of the grenades was similar to a signal cartridge and was loaded into the breach.

This tiny HE grenade weighed just 140 grams, and used a nose fuse.

The Wurfkorper 361 however, was inserted into the barrel using a special smooth-bore liner.

The grenade was created by attaching Eierhandgranate 39 to a plastic tube.

This had a range of 75 meters and used a 4.5 second delay.

The Egg Grenade used 4 ounces of Donarit explosive not a very big bang.

The firing mechanism is of the continuous pull punch in incorporating concealed hammers.

A switch lever is located on the top rear of the pistol frame to control the firing mechanism.

Turning it to the right allows only the right barrel to be fired.

With the lever in the center position, both barrels fire simultaneously.

Indicator pins located in the breech plate show whether the respective barrels are loaded.

A safety lever is located on the left side of the receiver.

The words Feuer and Sicher indicate the two positions of fire and safe.

Four specimens of the folding stock and removable sight are being evacuated to the Communication Zone.

Despite its ultimate lack of effectiveness, it does make for a fascinating study in idiosyncratic engineering.
