This is my "command squad" Rhino (extended hull as for a "C3" transport track) which is 2/3 of a represssor conversion. It was for my 501st legion themed
SM army back in the 5th ed days.
It's a rhino with a top hull piece extension made from 1mm plasticard sheet. The forward "stormbolter" turret is an old leman russ idler wheel with a hatch on it.
The fireports on the sides are made from strip styrene (3mm wide). With a full strip top and bottom, and short lengths in the middle to make the "windows")
