Enn'llien SteamTank (cargo cart) miniature for RPG

In a Pathfinder RPG campain, i'm playing a Half-elf Gunsligner/gunsmith and inventor named Enn'll Nothridge who's life work is to create a serie of steam powered medieval mobile artillerie ( in other words, tanks) which are named after him.

This one is a simple cargo car that can be towed behind one of the tanks of the same serie. The ramp isn't glued on and can be placed for easy loading of the roof without needing a crane.
