Over at the Lead Adventure Forum someone asked if anyone had any comparison information between figures from various ancients miniature suppliers.
I answered with the usual "Well these are about the same as those but these ones are a bit smaller" sort of thing, but on the grounds that a picture is worth a thousand words, I've got these two.
Left to right, we have figures from Black Tree Design, Renegade, Gripping Beast and Crusader. The Vallejo paint pot is for external reference. All the miniatures are based by gluing the metal base to a 20mm square of 40 thou plastic card, with a strip of magnetic sheet attached to the bottom, so this should be uniform (at least, it's intended to be!)
A closer view, without the bottle, gives more of a sense of the shape and proportion. Heightwise there's virtually nothing between them. Black Tree and Gripping Beast are more slender: realisticly proportioned would be a fair term, with Renegade significantly more "blocky" looking. Crusader are somewhere between.
My experience is that the within-range variation is very small: all the figures from one manufacturer match each other very closely. Between-range variation within the same manufacturer seems to follow the same pattern: I've got Saxons and Picts from both BTD and GB, and Picts and Saxons in both cases match extremely well size-wise within and between manufacturers.
