We continue to advance through the puzzle, although slower than I would like. As a novelty, I have published here a new chapter (here) dedicated to the Reinigungsgerät 34 variant with the extra 9mm brush with new information obtained that may be of interest to all those interested in the subject. In addition, I have also tried to further clarify the differences in the production of the Rg34 by Gustav Appel, so I added some more information in the chapter dedicated to this firm. I hope you like it.
Again, any help, comments or new information will be welcome...reinigungsgerat34@gmail.com
Thank you to all for reading me,
Antoni
