I just acquired my first Eureka Electro Magnetic! It's running good and I'm learning more about its design. However this one has a strange modification that I have not found on any Eureka. I believe this to be a German made version of the Eureka. There are no marking except for the A - R on the speed control. It's seems someone built a backing plate for the face that has multiple tiny clips on it. My assumptions are: Its a modern addition as these clips do not look circa 1910. The clips may have been used to attach a paper ring around the face for advertising purposes. The problem is that at each clip a notch was cut from the brass frame. I'm considering removing the modification but will be left with a notched face frame unless I can replace it. What are your thoughts on how I should proceed with this and have you ever seen this before. Maybe is a common thing that I am not aware of.
