This is a vintage comprehensive manual that accompanied a vintage canning machine used in large scale manufacturing of canned foods. It includes a full part list, instructions for use, and troubleshooting information. It shows wear and damage from age, use, and being stored in an industrial, factory setting. Imperfections include staining on the front and back cover, corner and edge wear, and yellowing pages. I have included detailed pictures of these imperfections in this listing. This manual is very rare and difficult to find. Please be sure to check all pictures to further judge condition. No returns. Message me with any questions, thanks!
