I picked up this ammunition box which I believe was for German WW2 grenades of some type. Theres a paper notice inside the box lid which I would like translated if possible. Here are some pics.

Thanks

This is an instruction for use how to arm a grenade. It says:

Fertigmachen der Wurfgranaten 15 = finishing of grenades 15 (it could be a kind of grenade for a mortar; Wurf means pitch or throw, but later it says to put the grenade on a kind of shooting gadget)
Zünder abschrauben = unscrew detonator
Sprengkapsel einsetzen = insert initiator
Zünder aufschrauben = screw on detonator
Granate auf den Schießstock aufsetzen = put grenade on shooting gadget (Schießstock is difficult to translate, I assume it is a gadget for shooting / firing / launching the grenade)
Bandschleife am Vorstecker lösen = loosen loop at linchpin
Vorstecker herausziehen = remove linchpin

Thanks ivbaust, looks like a rocket grenade of sorts. I assume its WW2 era.

the Wurfgranaten 15 is a small rocket propelled shell, fired out of a portable, one man operated launcher,it had a small base, an open railed tube, and a small telescoping front 'leg' as a monopod for support, that locked into two other tubes to form an inverted triangle base

Here's a picture (stolen from http://lagrandeguerre.cultureforum.net/armes-et-accesso...fer-1915-t3647.htm):

Thanks Kursk & Herr Wolf.

I believe this is the shell that was fired from the launcher
