Here's something more unusual:

Model kit company Meng makes cute deformed versions of WW2 tanks under the label "World War Toons." I got some to turn into Grot Tanks, and figured their French Char 2b might actually make a decent Imperial vehicle. I decided to turn it into a Hellhound, since it's the closest match for the Char's shape. The size is close, but not perfect - length and height are fine, but the hull is not wide enough.
