Here is an assortment of Camco catalogs that have been scanned for you to download and enjoy. It bears repeating that the catalogs were rarely updated and as such you will notice things like recycled photographs and layouts. They are still a useful tool when armed with this perspective.
Drum Archive.com was very kind to let us link to their page of catalog scans, however it should be stated that the years attributed to the various catalogs are certainly an estimation since the catalogs themselves are undated. Enjoy!
