The figures are Old Glory from their Italian Wars ancients line. I've added the characteristic Samnite shields which I ordered from Crusader Miniatures. An aside about Crusader Miniatures, their customer service I found to be excellent, even ordering directly from the United States. I'm putting these down in the painting totals as 25 figures. I painted one extra musician (not shown) which will be used in an upcoming re-basing effort.
The figures are comprised of three stands of peltasts, classified as 'soldiers' in HATG and three stands of psoli classified as 'foot skirmishers'. I've mixed in plenty of striped tunics and wildly colorful shields and helmet decorations to represent a Samnite colorful legion as opposed to the Samnite linen legion. The latter will be the subject of a future painting project which is currently on the table.
