This is a wooden crate that was made to hold one sleeve of German 7.92mm

ammunition.  A standard crate holds 5 sleeves.  This crate held several different

types of ammo.  The last was apparently 1944 dated S.m.E.  At some point,

it held the very rare S.m.K.H (super armor piercing) ammo and appears to have

held several different boxes of S.m.K.H over a period of time.
