Very rare German Third Reich super armor piercing ammunition.  This ammo

is some of the most difficult to find as very little was apparently made.  The red

primer identifies the S.m.K.H. rounds but when placed in a stripper clip, the primer

is hidden so they put red paint on the stripper clip to identify them.  The "i. L" on

the label means the rounds are in stripper clips.

Patr. stands for patronen which means cartridges.
 
S.m.K. means armor piercing (Spitzgeschoss mit stahlkern).  H. apparently means hardened (Gehartet).
