So I got a big Warzone Brotherhood lot. Most of it was straightforward, but there were a few pleasant surprises that I didn't recognize.
The model on the right in the first pic is a Mutant Chronicles Keeper of the Art minus his stabilizer backpack.
EDIT: Found out the one on the right is indeed an Arch Primate with HMG. Definitely rare. I hope I can get the beads off; it appears the previous owner was using these as Noise Marine proxies.
EDIT: These next two pics are currently sold by Alternative Armies; they are Ion Age Retained Knights now. All of these models are available from their Ion Age range. Would not recommend for those looking for modern, clean, technically precise models, but they are absolutely dripping with old-school charm. If you want some models straight out mid-80s sci-fi, they are fun sculpts.Thank you for the help- that was quick!
