As always these are not mine, things found that might be either burried in the depths of history or forgotten about. First up is Col Corbane and his take on a Hydra anti-aircraft defense vehicle which was recently finished and you can see here. Corbane has since taken a leave from the world of blogging, but already came back, so give him a comment to let him know we care!
Second is a command and control vehicle from the Warseer boards circa 2008.
Last but not least is a gem of a turret conversion I found over at the sporadically updated Bridge of Khazad-Dum where Jonathan puts together some excellent work.
