Ernst Kaps grand

[Jurgen Goering]

Any large, heavy plate is sometimes referred to as "Panzer Platte" in 
German.  If it were cast out of a higher grade, more expensive steel, 
it would surely be designated "Stahl Platte", to set it apart from a  
"Guss Platte" (cast iron plate).  So much for the language and 
terminology.

But who knows exactly what Kaps' plate were made of?  One definite 
answer would be the results of a lab test of a piece of the plate...
