Thanks, guys. I enjoyed putting the Trumpeter RWS together - not as nice as the AFV Club version (and not as many useful spares) but nice enough. The lenses are different color and match the real world lens reflections, well - although they're not visible in the pictures. I used a strip of flexible resin ammo belt that claimed to be .50 cal, but looks more like 7.62mm. There's a tracer round every 5 rounds, but of course, only one of the three on the strip is visible.
Jeff, I left the existing fuel tank caps in place (there's another one on the glacis) since I would expect it to be a bit of a gas guzzler. I even added a section of fuel line in the interior (made from sprue) to the upper front left of the driver's position, directly under the filler cap.
I noticed that some of the pencil marks on the armor plates are visible under the paint/grime... I was about to repaint the areas, but they look pretty good.
