The EARLY MAKERS TRADE MARKS thread... lost and partly restored.

[fernando]

These (three in all) examples are in principle Spanish. They were forged, not cast; those appeared much later. The four dots were surely the mark of the workshop but, as you know, very often early marks represented symbols, magic and so. I remember now who said these were 15th century marks.

I would not associate these dots with the ones in your sword; after all, dots are a symbol easy to occur everywhere and in different periods, as also in more complex setups, like in edged weapons.
