However, there's much to be said for smaller scale miniatures, not only in regards to price, but also the impressiveness of fielding vast armies on the tabletop. And for a horde army like The Skaven, this is something worth considering.
Games Workshop made it first foray into Fantasy Wargaming on a smaller scale in 2000 with Warmaster, written by none other than Rick Priestly. It is a system highly regarded to this day, and in many ways is a direct precursor to Priestly's current historical wargame series for Warlord Games starting with Black Powder.
A Skaven army was introduced to Warmaster in 2003 with the 17th issue of Warmaster magazine:
WTH is with the smaller scale miniature companies not having any pictures of their minis? Seriously. It's rampant. I'm not talking about the difficulty of chasing down online pics or catalogues of OOP minis from the early 80s (something I've done quite regularly for this blog series and the Skaven Collector's Guide), I'm talking about currently operating online companies that just list the titles of their products on their website, and if I'm lucky, sometimes I can find a pic or two of some examples painted on blogs. This article took maybe 3x the amount of time to get together just because it was so impossible tracking down any kind of decent pics. And I get it, 10mm is harder to photograph, sure, but we're talking about online stores trying to make money, right? This isn't the mail order days of the 1970s anymore. I can't imagine buying an entire army sight unseen, no matter how cheap it is. WTF folks?
Irregular Miniatures
So, Irregular Miniatures it turns out offers two Ratmen armies, one in 6mm and one in 15mm. I've only been able to turn up one example from each scale, but they look pretty good (well, the 6mm pic is kinda blurry).
Pendraken/Kallistra
Kallistra are a Nottinghamshire, UK producer of miniatures who have been in business since 1999 (or, at least, that's when their website domain name was registered). They are included here because the Ratmen they offer (advertised as 12mm rather than 10) are actually the same sculpts as the Large Pendraken Ratmen (and their website has pictures). From what I understand, Kallistra licensed the sculpts from Pendraken, and the only major difference is that Pendraken casts the minis individually, while Kallistra casts them on "strips", much like the Warmaster figures.
So, whereas the Pendraken site has no pictures, and the Kallistra site has very small pictures, a blogger by the name of Warren Abox (who can also be found on the Lead Adventure forums) has posted online some exceptional pictures that show off at least some of the line in decent detail.
East Riding Miniatures
Magister Militum
Magister Militum offer two ranges of Ratmen, in 10mm and 15mm, and they are in general pretty good looking. They remind me somewhat of Grenadier's Ratscum.
Splintered Light
Before returning to the world of 25-28mm, lets take a brief pitstop into the 1:72 scale figure range, a scale I really like as a nice balance between affordability and detail but hasn't completely caught on with the fantasy crow just yet so options in that regard are pretty limited. The only ratmen I could find available at that scale come from Caesar miniatures, and while functional and cheap, I'm not overly impressed with the sculpts, especially in comparison to what some companies have managed in 15mm or less.
Just came across these delightful fellows from Microworld Games:
