Hi Michael
There are several pages in Rider Vol #5 and Rider Vol #7 on the Grunow Model 6C. It's also listed as Model 660, 661 and 662. The schematic is in each of the Rider volumes.
Try your local library as they often can get Rider information. You will want copies of several pages as schematic, layout and alignment istructions are included.
