Yes, I I agree. This is most likely a picture of yamanites but could possibly be The ancient amezigh ( Berber) Jewish community of the Atlas mountains. We know about them but not as much as we should. I think it's because they mixed with this Sephardic community.
That is a famous picture of Yemenite Jews making Aliyah to Israel with only a Torah scroll and few other belongings. But thank you for the effort nonetheless, which I appreciate and I'm sure many others do, too.
