Thank you so much Jeff, Fernando and Jens!
Jeff, you da man!!!!
!!!! Those are fantastic references!!! and how the heck did you ever find a copy of Cronau?
The kaskara is an excellent example of these trade blades that entered North African, Arabian and sometimes Indian spheres, and the marking you show is terrific proof. It seems that makers in Solingen would often inlay these inscribed marks with brass, the running fox from 16th century on had this application often according to the Wallace Collection. The red gold is especially interesting and I wonder how often gold was used. With it being gold it seems likely this might have been something more than a trade blade!
I have seen interesting inscribed floral designs on the blades of some Mexican espada anchas of the 18th century that held yellow metal...I thought it was brass but I suppose it might have been gold. I have also seen the yellow metal inscribed running fox on a Hounslow hanger of 17th c.
Does Cronau refer at all to the three crosses or show markings of them? Also, the multibarred crosses that usually appear at the terminus of fullers on European, especially Spanish oriented Solingen blades. These look like the cross of Lorraine, except with more bars and certain fluorishes at the base.
Thank you again for the great entries and illustrations!
All very best wishes,
