Have received information today from a collector in South Africa that 2 of the Bedouin series watercolours have been found in a local 2nd hand dealership and depict scenes in the vicinity of Damietta. They are framed and in good condition with the same style signature common to this series.
I have seen other Barbaro works available in South Africa so it seems that they have probably travelled down from the north during Colonial times. Worth looking out for if you're in that region.
Reports of any findings welcome.
