Not a double post, but you asked what I was going to ask, you mind reader!
Nice builds there Jarobinson!![]()
Those are what the Dreadnoughts looked like when they first premiered in 40k back in '89-'90. At the time, they weren't walking sarcophaguses, but machines that the Imperial Guard hardwired some poor soul into for the duration of the battle (see diagram).
Most 40kers who know them call them "Peanut Dreadnoughts"
AND, Very nice build, BTW.
