Sorry for answering in English, I don't have my Arabic keyboard in the café where I am answering.
This picture is indeed much more convincing and seems authentic. The catalogue number 31544 indicates very old recordings, Ahmad Hasanayn supposedly d. around 1906 has 316XX recordings. So these would be circa 1905-1906 recordings of Bamba, probably of low technical quality, which explains why they are not mentioned at all in the 1913 catalogue.
Has anyone seen other Bamba Odeon recordings ?
