I'm starting to build a Makhnovist army and have found the threads on the topic extremely helpful [as is the whole forum...an astonishingly wide and deep resource]. I was wondering how the Copplestone Czech Legion infantry would look painted as peasants: the tunic seems from the illustration to be able to pass for a peasant blouse/smock. Or am I wrong?
I'm sure the Czech Legion figures could work. Painted in suitably shabby and mis-matched colours, they could definitely pass off as makhnovists.
However, I also recommend buying Copplestone's Russian Partisans and Ragged White Russians as well (just be sure to file off the shoulderboards for the Whites). Makhno's forces weren't exactly known for their high-quality uniforms, so having a mixed unit painted in a variety of greys and khakis would work best in my humble opinion.
