I picked up a couple of photos on eBay a short while ago that were supposedly from the estate of an officer who served with the 5GRzF; this one shows two officers in the foreground, one evidently not a member of the 5GRzF. Two names are written on the back, but they are not numbered, so I'm assuming that the upper name (Lt. v. Rohdem) is #1, meaning #2 would be Lt. Graf v. Rothenburg.
