Mark emailed me on the subject of size compatibility of various 20mm and "true 25mm" figures, so I have knocked up another of those strange green comparison photos. Since I often get involved in this kind of conversation (and since my view is as subjective as everyone else's!) I thought the pic might be of wider interest.
The particular thread in my correspondence with Mark has been how successfully SHQ/Kennington figures might blend in with (for example) Hinton Hunt. As the photo shows, I think, they match pretty well, though you have to beware of the occasional midget, such as the Spanish hussar marked with an asterisk - for some reason I never understood, all the Kennington Spanish Napoleonics are a bit small.
