I have all of them. TSSD do not go with Airfix, Marx, and the other traditional 54MM Sioux. The CTS mounted Sioux will go better with Airfix and Marx. TSSD Sioux have very thick bodies and look out of proportion to the Marx and Airfix. This also goes for the BMC Sioux. They are decent but also won't go with TSSD. The TSSD plains indians will go well with the Paragon Sioux, very similar sculpting and size.
I will try but I can assure you that the CTS mounted Sioux will go fine with Airfix and Marx Plains Indians. Marx, CTS, BMC and Airfix Plains Indians all go well together. Same with the Marx, BMC and Airfix 7th cavalry, almost perfect match. They won't go well with TSSD and Paragon because the sculpts are slightly taller but also the bodies are thicker. Now, some collectors don't care about that but there is a distinct difference between Airfix and TSSD. Get the CTS mounted Sioux, not real expensive and you need more mounted Sioux. Marx did only 1 mounted pose, Airfix did 2. BMC did 4 but BMC are not as well sculpted as Marx and Airfix. Decent, but I'd rate Marx and Airfix as Excellent and BMC as Good. The CTS mounted Sioux I also rate as Excellent. You won't regret getting them.
Yes, both the Airfix cavalry and Sioux warriors are a perfect match with Marx cavalry and Sioux.
