Ok this is getting interesting a fellow forumite emailed me this photo today..
Clearly Very similar piece & workmanship. Cartridges look like heavy calibre late 19th century pieces to me.
Apparently from the Sheikh Faisal Bin Quasim museam in Quater. Where its displayed as a c.1910 Yemeni piece in solid silver according to my friends recollection.
So Arab manufacture seems extremly likely? Perhaps Yemini even? depending on the Quater museams research or provenance?
What makes it look non Arab to your eyes Michael? Could it be from a particular ethnic group or culture perhaps?
