This is excellent news showing Latten style inlaid hogsbacks which would usually be European crafted ? .... I'm not sure about the M as it appears to be the Majescule A. Naturally a sword could arrive with marks already completed and then added to by African smiths...

For sure the ADABAL is decorated in snake forms ...commonly seen in these West African decorations...i think in Ashanti design...although it can be imagines that a line up of snakes in front of the crossguard would afford some mystical Talismanic protection to the sword hand...
The three dot accompanied in the eyelash or hogs back also happens to be an Hausa letter k .
In conclusion it appears that some parallel exists between North African design and the influx of European blades and that Tuareg and others seeing the similarity in design have been inspired to copy in their well known counterparts including some of their decorative alphabet capitals... I illustrate the last point with a chart showing a very similar letter to the European Fly mark...Third row second from the end
and the cross and orb on line two...
