I’ve always liked the Ork Gunwagon, which was one of the first Forge World models that was released and was one of the first that I purchased. After a while Forge World started releasing them with bigger more powerful weapons.
This is a Forge World Gunwagon with Big Shoota
Another Forge World Ork Gunwagon, this one is armed with Big Zzappa
