Hope I don't need to translate the complete site!        https://www.holzwerken.de/museum/hae...erdinand.phtml
BTW, great work Steve!

 Good work Detlef! Yes, the original company seems Ferdinand Esser, but sometime in the late 1800's swords and machetes showed up marked Fernando Esser. There are a lot of swords out there with the mark "Fernando Esser Elberfeld", above "Acero Fundido" (cast steel?) over "Garantizado". 
 From the webpage that you cited:
"In 1889 a branch was founded in Hamburg, which had emerged from the company Wm. Ahrens & Co., 1890 a branch in Paris. In 1894 Ferdinand Esser died.
The company belongs today under the name "Fernando Esser & Cia. GmbH" to the brothers Mannesmann AG in Remscheid. 4) "
