Welcome to the Strelets Forum. Please feel free to discuss any aspect of 1/72 scale plastic figures, not simply Strelets. If you have any questions about our products then we will answer them here.
Thanks, Pedro. The figures in overcoats (representing the Irish Brigade, which famously assaulted the Heights without shedding their coats) are mostly metal -- most, if I remember correctly, from the old Musket Miniatures line, now discontinued, I think. There are a fair number of plastics mixed in, using the two in greatcoats from the Accurate Confederate Infantry set, and one (with a head swap) from the Italeri Union Infantry. I confess I've forgotten where some of those came from, since I've been collecting ACW figures for so long.
