As part of a recent purchase I picked up some nicely painted 28mm Greeks from the older Wargames Foundry Greek range, that are a little smaller than the hulking WotGs that I collect. I've rebased these on 12 cm wide elements for Impetus (or for that matter To the Strongest!) and they are for sale at a modest £50 plus postage for the pair.
I also have another 8 similar but unpainted Foundry Greek riders for £12 and 19 primed 1st Corps Persian Immortals for £8. If you'd like them, please drop me a line at the email on the blog header!
