I have worked on several reback repairs, but not any on half bound books until recently. What I mean by half bound is that the spine material differed from the covers. For this particular book, the spine was book cloth and the boards were covered in paper. The text block had fallen out of the case and the spine was only attached to one cover.
Once the book cloth was removed I lifted the paper slightly, so the Morike will fit underneath it. Then I proceeded to attach the text block and repair the case as usual. This is the completed repair.
