The larger box in the picture had a few dings that I hammered out, but I could not remove that warp in the front of the lid.  It looks better in person than in the photo.
I used a silver Sharpie marker to touch up the plating.  I use the Sharpie on my 50 year old motorcycles also.  Another great touch up for plating is RubNBuff silver.  It's a wax product that can be applied with your finger, a Qtip or thinned and brushed on.  Applied on cadmium plated bolts its hard to tell its there.
