Good morning. I can confirm that the officer with sword is definitely Foundry and is from their pack PER025 ( Sparabara Command). I suspect the spearman is from PER09 (Sparabara Spearmen). Rather confusingly Foundry have 3 Achaemenid Persian ranges. Two are on their main website and are called something like "old" and new" . The third is on their "Casting Room Miniatures" website. The packs seem sequentially numbered but jump between ranges/websites which doesn't help at all. The "old" range are relatively small ( 25mm?), the new range larger and compatible with their "World of the Greeks" range. Unfortunately not all the packs now seem to be listed. For instance PER025 has disappeared, hence your identification problem! I bought an entire army ( including the elusive PER025) at a 50% discount from them at a show last year, so wonder if they discontinuing packs whose moulds were shot?
Anyway, hopefully the mystery is solved
