What a rich history!
This J. Faber seems to have been stored it in the wrong box. The Arabic text is exciting because it is incursive and I believe it relates to a Sausi dialect rather than traditional Arabic language. It consists of 3 words. The first word reads “somm,” which translates to “poison.” Poison here should refer to the graphite. The second word reads “somar,” which is probably a slang/dialect of pronouncing the Arabic word “asmar” in traditional Arabic, which translates to “black.” The third word is “Almani,” which translates to “german.”
