This is perhaps a long shot, and probably doesn’t help to narrow down the origins of this interesting padlock, but I have a different suggestion for the use of the name Gordios.
Huw is right that Gordios is a name of Greek descent, however looking at the logo behind the name on the lock, which strongly resembles a knot, I can’t help but wonder if this is a reference to the Gordian Knot.
In the legend, the Gordian Knot is used to secure something in the manner of a knot, and is composed of “several knots all so tightly entangled that it was impossible to see how they were fastened”.
I am wary of posting an image here due to potential copyright violations, but an image search for Gordian Knot throws up images of knots and symbolic representations very similar and in some cases identical to the logo on the padlock.
