I have a few of these so I just got up to take some quick photos for comparison. I'm a little biased because I've always believed scale to be more of a suggestion rather than a law, but I think they fit just fine. The marauder figures and for example 4th ed. Perry Empire sculpts will definitely dwarf them a bit, but I think they fit in pretty well with C46 men at arms and pre-slotta figures, though in all cases the Ral Partha sculpts have more realistic proportions. Some of the figures are skinnier than others - that crossbowman is pretty titchy.
Left to right: Citadel pre-slotta wizard, Ral Partha Pikeman, Citadel C26 Halberdier, Ral Partha Handgunner, Marauder Flegler, Ral Partha Crossbowman, Citadel F4 Mercenary.
