Dime el Aterro

[Gavin Nugent]

I am hoping someone can point to exacting origins of sword blades carrying the stamp

* Dime ~ El * Aterro *

* Dime ~ El *
* Aterro*

I have seen it in both the layouts above with the first appearing to be much older and with differing text and star stamps than the second one...perhaps an indication that the mark or guild has been around for a very long time....I am guessing 17th and 18th centuries.

Any help or direction would be appreciated.

Thanks

Gavin
