Dime el Aterro

[fernando]

German blades ... why not ?
The Spanish possibility starts to evade.
However after a few thoughts, the word composition is so otherwise that i would not see it as a corruption or mispelling of a Spanish (Castillian) sentence, but a smith fantasy.
The odd separation, the wrong conjugation, the so unusual & and all that.
... all these "Aterro" variations coming from the same spot, naturaly.

I have received the last of three advices i requested from Spanish sword connoisseurs.
Again the Spanish origin for these blades was a possibility put aside.
A different approach was instead brought to consideration, as being the inverted position, that is, Spanish blades being imported from Germany, when home production did not suffice the needs, and a clumsy conversion of a German text to Spanish.
Well, a new perspective .

I was guessing. Glad to have more knowledgible folks support the possibility. Now, what is the connection with a German-made, Spanish style blade ending up on an East Indain sword? Trade routes??
