I did these back in the 80s. One is a converted Imrie/Risley figure of a 9th New York Hawkins Zouave. I added the kepi head and havelock. The actual uniform for the Salem Zouaves is in the Essex Institute in Salem, Mass. The last time I saw it the blue cloth had oxidized to a green color.
Another conversion is this couple. The Zouave is a Stadden and the girl is a plastic Mokarex figure given a new head. from a novelty figure. My mistake was using a figure in ball gown and painting it a dark color. Not correct for daytime nor the season. maybe someday I'll repaint her.
The "SZ" on the canteen can be seen in a period illustration from a book on the 8th Massachusetts published at the time of the Spanish American War.
