Tom, I have some of these same poses, painted differently, so they might be castings..I got mine off of Ebay, years ago. There was an outfit from New York ( ? ) that sold these poses as well as Brits. All were excellently painted in a high gloss..I have 3 sets from the different Zulu regiments..If needed for comparison , I can post photos..Michael
In looking closely at your figures and mine again, I am pretty sure they were all done by the same east coast outfit. Michael
