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 a black coating on the bullet 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).   

The second line shows that the cartridge components were assembled by Polte Armaturen-u. Maschinenfabrik A.G., Werk Magdeburg, Sachsen.  It was delivery lot 132 of 1940.

Nz. Gew. R. P. (Rohr-Pulver) means hollow tubular powder.  (1.8, 1.3, 0.2) means the powder tubes are 1.8mm long, external diameter of 1.3mm  and internal diameter of .2 mm.  The powder was made by Rottw, delivery lot 4 of 1939.

Patrh. means cartridge case.  The "S" means brass case. The "*" means the composition of the brass was 72% copper. The "P" means the case was made by Polte Armaturen-u. Maschinenfabrik A.G., Werk Magdeburg, Sachsen, delivery lot 8 of 1940.  

 

Gesch. means bullet, made by  Polte Armaturen-u. Maschinenfabrik A.G., Werk Magdeburg, Sachsen, delivery lot 113 of 1940.

 

K stands for kern or tungsten armor piercing core, maker is Ro.F and is the initials for the company but the company is currently unknown. Delivery lot 5 of 1940.

Zdh. means primer (Zundhutchen).  88 means the primer cup is made from brass as introduced in 1888.  It was made by Selve Kronbiegel Dornheim A.-G., Sommerda (S.K.D), delivery lot 65 of 1940.  I'm not sure what the "j" is after the lot number unless it might be a sub-lot.
