Thanks everyone! Appreciate you guys taking the time to look and comment.
@Us3Less, the bases came from the first batch of guard I picked up - their previous owner had plans to base them on the plain transparent acrylic, but never got around to assembling them. They were free and they were there and then the rest of the army had to match! The flamer guys are Forge World Solar Auxilia Flamer Section models - I think they are really lovely sculpts, like the entire range.
@Illumini yep, it's a bit of a gotta catch em all approach - if I can get my hands on Mordian, Tallarn and Praeteorians, I might even call it a day...but I love the old 2e ratlings and ogryns as well! hmmm...it never ends!
