if you go to graflex.org, look for bert saunders he is a retired expert and
can advise you about what you might do. you can also search there
for mr lustig's address / phone number. he doesn't have internet service
but will gladly talk to you on the phone about repairing your slr ...
there are others as well, you will have to search around to find them.
but those 2 come to mind first, and they have very good reputations when it
comes to graflex repairs.
