Imperial German WWI Stick Grenade

Inert 1917 pattern stick grenade has stamped metal warhead which retains ~30% field gray finish blending with dark patina where worn.  The instructions stencil remains mostly legible.  Turned wood handle has the fuze time promise of "5-1/2 SEK" maker's stamp and partially legible date.  Grenade has base cap as well as the ball and fuze pull.  Unlike many of these that we see, the screws holding the warhead attachment collar are original to the grenade and not later replacements or overly-boogered from the deactivation process.  Screw cap at the base opens to reveal porcelain ball pull and cord.  $400 - $500
