Steven,
I think quite a few of us would like to see some of your x-rays of
shells. Are you able to scan them into your computer? There was a site
on the web that featured such photos. I saw it quite a while ago but I
will look around and see if I can find it again. You two probably would
enjoy comparing notes. I'll let you know if I have any luck.
