Nice work there
. The arm-guard looks like a distant relative of a Turco-Iranian bazu band. Although I vaguely remember an Indian vambrace with a similar structure from somewhere. The mail and plate cuirass has a similar structure to a 16th century Turco-Iranian Krug, however the shapes of the actual components are different. Islamic oriental mail and plate armours tended to prefer more geometric shapes like circles, rectangles and squares.
Here is a 17th century Turkish vambrace or bazu-band (from the Karlsruher Turkenbeute collection). Most contemporary Iranian and Indian vambraces would have had a similar construction but a different style of decoration. Vambraces of this type were used in the middle-east from the late 15th century to the early 19th century.
This is a 16th century Ottoman krug or korazin from the Royal armouries in Leeds. This type of armour was probably used from the early 16th to the late 17th century in Iran, the Ottoman Empire and Russia. In Iran and India the Krug was superceded by the chahar-ayna cuirass in the late 16th century.
This is another type of mail-and-plate armour, variants of this were used in the Mamluk Sultanate, Ottoman Empire, Iran, India and Russia from the late 14th to late 18th century AD. This particular example is Turkish and is in the Royal armouries in Leeds:
Finally if you haven't got these two books already then I would recommend them. They're a bit old fashioned and occasionally downright out-dated, but they're cheap (especially if you buy them second-hand from abebooks.com) and have lots of pictures, so they are a good starting point:
