That Commandante is a very good likeness of Mika Etchebéhère, but she commanded a company in the POUM's Lenin Battalion.
True, that particular sculpt is based on the pictures of Mika Feldman (later Etchebéhère) I could find. Take it as a small-sized monument to that outstanding woman.
And true too, the real character actually lead a column of POUM militia
men - it's up to you whether to give the sculpt that very same use, or to make her lead a militia
women unit...
Best wishes,
