Didde Web Press Unit Register & Water Trim Assy. If you’re looking you know what these are and where they mount in the Console. These are the Older style with the Analog type Register Scales, the later type had LED displays and will work in either application. I haven’t cleaned them up to look pretty, they are just like when I removed them from the Console. There are four of these units for sale but I’ve only photographed one of them as they are all in similar condition and from the same printing press. Compatible with several of the Didde Press models.
