I was reluctant to open it up even before you asked markf, however we must know all the facts. I opened it up, now question wanting to part with it.

All serial #0042 except 1 #0999

I remember "The Chip Rack" having 1 in the series at 500 lt. blue and 500 dk blue, but it wasn't this one "Air Corps US Army"

Is there more to this story?
