Pete,
When the photomichrogragh arrives I will scan it into a file and share it
with whomever might want to look at it. I can send it as a JPEG image and
attach it to a note for those who request a copy. I will promptly return
the original to you.
It is good of you to share the information.
Thanks, Art
