I wanted to ask if we have any surviving examples from Acheamaneds body armor ???? like Iron scales, shoulder armor, or anything at all????
Hello again. As much as I'd like to have a great detailed answer for you, I'm afraid the answer to this question is short and pretty disappointing. For other readers' benefits I can point to my previous answer where I discussed how most of our information about Achaemenid armor comes from artwork and written sources.
There are just three or four examples of physical Achaemenid body armor.
A wide range of iron, bronze, and gilded scales of varying sizes have been found at Persepolis ( E. Schmidt 1957, pg. 100/132 digital and plate 77/pg 322 digital )
A single clump of iron scales from Pasargadae
A few iron scales found at the cemetery of Deve Hüyük in Syria, which I cannot find accessible pictures for but see: Peter Roger Stuart Moorey, “Iranian Troops at Deve Hüyük in Syria in the earlier 5th century B.C.” Levant 7 (1975) p. 115
Possibly a few scales from the Palace of Apries at Memphis, Egypt which was still in use under the Achaemenids but the exact provenance of the scales is uncertain. We just know it was a design favored by the Achaemenids.
That's unfortunately the whole catalog.
