• Early model, green/black on ochre
• Early model, green/brown/grey patches on sand
• Late model, green stripes on ochre
• Late model, green and brown "flames"

The model is really difficult to assemble, so much so that I have to wonder what the workers thought of the real ones as they assembled them.  There are so many small pieces and odd angles.  I have put in bulkheads in an effort to keep the parts straight and aligned.

There are two hulls.  The early hull had two fuel tanks - one in the bow and one on the left side next to the driver.  These were found to be vulnerable to fire in combat.  The late hull added two external fuel tanks on the hull rear.

Early and late hulls had applique armor added to parts of the front and sides.  I have included these parts in my models, though they aren't strictly necessary.
