Not definitively, no. It all comes down to the measurement used for the ‘120mm’ or whatever. Is it the height to top of head or eyes? Of a six-footer or an average person for the period? Scales are much more useful because although some kit (such as helmets) is made in more than one size, most (rifles, for example) is not. It looks v odd to have two ‘120mm’ figures next to each other with differently sized MP40s in their hands.
