these cameras aren't difficult to fix. I bought two Speed Graphics a few years ago sold as parts to make one good one only to sind one was pre-Anniversary the other a Pacemaker and there's no common parts. I found new Guides on ebay for the rear rails on the Pacemaker, the secret is they are shimmed to allow smooth retraction of the standard. Both cameras are now rebuilt. With a little patience you can get the camera back full functional.
