...I'm starting to realize that worrying about scales and size compatibility for human figures is a dead end. I'll try a couple of the commercial addon sets but if they don't fit, they don't fit, and I get to practice scratch building...
Exactly. I prefer 54mm figures, and as we've all noted, there are variations in interpreting what 54mm is, across various manufacturers and across the years. When I have two figures to use, I look at proportionality when I decide whether the two are compatible. For example, I paint Staddens and Tradition figures, and Imrie-Risley. Imrie-Risley are closer to a "true" 54mm (which they bill also as 1/32), while Stadden's figures are more robust (though some of his line were closer to 54mm than most of the others). If I can put the two figures side-by-side in a display, and despite differences in height, they look "normal", that is, the heads and hands appear to be within the normal variation we find in any population, if the legs and arms are normal (Kaiser Wilhelm's left arm notwithstanding), then I'll use them. If they're way off, then I don't. As I mentioned above, among today's collector's figures, 1/30 scale has become common, and popular. A figure from King & Country, for example, is just too big to be placed alongside a figure in 1/32 or 54mm. It's not just height, it's the proportions. They are noticeably bigger in proportion.
It's just a hazard of the hobby, if you will, if you want or need to mix and match items from different manufacturers. And there isn't really a "right" or "wrong", unless the manufacturer states explicitly that a figure is supposed to represent a person of a particular height (Seydlitz was tall, for example, around 6' 3"), and for the scale or size that manufacturer labels his figure, it's just off. It
is easier to work out the accuracy with scale rather than size, in that case, since scale is expressed as a ratio. But you're right, it's a dead end. I eyeball the figures, and if they look right next to each other, then together they go.
Prost!
