[ARC5] Interesting?

[David Stinson]

What am I missing?
The "bolts" mounting for the nomenclature tag is very 
common in these later builds, especially Colonial.
The one on the left looks over-tightened during assembly
but otherwise likely original.
One of the forward screws is silver instead of black.
Another is missing on the bottom.  These seem minor.
But I haven't had my second pot of coffee yet so 
there's still a lot of fuzz between the headphones.
