Was looking for some information on the different models of the 39 Eierhandgranate, and came across this very interesting site. It show some stuff they made shortly after the war, using handgrenade parts. Check out the lighter made from the Splittermantel! And the oil lamp that has a base made from Kfz tail light! Pitty the site is in German, and can not be copied for translation.
