My earliest lead armies were Persians and Greeks. The initial Persian forces concentrated on Garrison cavalry and Minifigs infantry. It seems a bit strange to me today that the 64 cavalry were considered to be enough! Hate to think how many Persian cavalry figures I've got now..
At some stage (later 70s?) I added a few standard bearers. This was a period when I liked big standards.
When the PB Range came out my interests went towards Alexandrian Macedonians and Later Persians. As I recall I should have 20 Cardace infantry, so not sure where the rest are. This lot are again in their mid 70s guise.
For some reason I had 60 light archers. Many of these are now in Sparabara units, but some are still serving as light archers. Probably an 80s or 90s paint scheme, in those days I often repainted figures. Still do.
The slingers are later issue Minifigs as I didn't originally have any.
It was a time of no shading or gloss varnish, but lots of squares and stripes.
