Some of the items you explained weren't evident in the pictures. Thanks for the explanation.
The reason I mentioned the chipping is that you show a fair amount on some surfaces (turret top, rear deck, and front hatch plate) indicating that this is not a new vehicle, but it doesn't look like the fenders have a scratch on them (again, it may not be showing in the pics). You'd expect some wear and tear from bushes, trees, crew, or mounted infantry.
The screens are the same story. With enough traffic to chip the paint on the rear deck you'd expect some minor damage to the screens. As Ivanhoe mentioned they did get stepped on, the crew pulling maintenance may have knelt on them, who knows.... So, your 7 yr old sister is working for the French resistance?
You should do quite well with your effort here Trevor. Basic, huh? Don't get used to it. You keep building like this, and you'll be intermediate in no time!
See you in Fredericksburg
