John Craig of Craig Camera sells user and repair manuals -- literally
thousands of them. If what you are looking for isn't on his website
<http://www.craigcamera.com> you can contact him directly and request
it. <mailto:john(a)craigcamera.com>

On his repair manual page he lists various M645 models -- just scroll
down to the "M"s <http://http://www.craigcamera.com/lit_newrep.htm>

He sells both originals and xerox copies, often (but not always) for
less than they can be found on ebay.

Hope this helps.

I haven't gotten anything from John for a while but
used to do a fair amount of business with him. I can
recommend him. He is honest and friendly. He also often has
stuff that is not on his web site so an e-mail or phone call
is worth the effort.
