I recently picked up four 25mm elephants on EBay. They had been advertised as Sassanid but looked more Classical and I tracked them down as Carthaginians made by the late lamented Garrison. They came with a job lot of slingers, jevelinmen and a couple of Persian-style spearmen, as well as three crewmen for each animal. I think they are my best ever EBay find.
The elephants needed a fair bit of filing down and filling, but I am delighted with the end result. Lovely animation and they fit very well with my mostly Minifigs army. I will use them to represent Successor elephants but am sorely tempted to buy more 25mm Carthaginians.
One down, three more to go...
