Re: 840c diagram

I am more than happy to start a section of internal views for the
purpose that Ron and Gerry are suggesting. The more information the
merrier. I suggest that you limit individual photos to about 200-400k
size which will be fine for uploading onto the website and will give
good resolution. Send them to me at my e mail address above (or look
on the website).

Regards
