I have alot of pictures of my 2013 3895 being built and those around it at the factory. I requested pictures of it being built when I ordered it. It took them from Oct '12 to Feb'13 to get it done and shipped out here to California. I have the full body paint and that took the longest, because they send it out for paint and then it returns to the factory for final assy before its ready to ship out.
Maybe you will be able to see something that you were wondering about in the pictures.
Here are just a few for now.
