Just some more info about this.
Thyssen Krupp was not existing when the 4 Symbols came out.But Krupp was ! Krupp (company and family) only got the 3 Rings as their symbol.Not the rest of the pic shown here.
They made the best steal (tanks WW2).
So all this even fits better ! Krupp was based in Essen /Germany.LZ played one of their best concerts there as far as people can remember.
Steele is a part of Essen.The symbol of this place is also a 3 Ring but with the one below.When I rambled around there in childhood times I always moaned:"Steal away,Rosy,steal away!"
I suggested that Steal and Steele were related words.
