Sariel,
although I cannot readily think of where you may find examples of ingots, I
can tell you that the composition that you found is very similar to the
composition of several bronze artifacts excavated at al-Midamman in Yemen,
the paper was published in JAS 29 (2002). The material is expected to be
dated from around the same period as what you are looking at. if you have
problems finding the paper I can forward you a copy.
