Ken Musgrave's drawing of the Graf und Stift should help any scratch builder. I am not aware of any 1/72 kits, but somewhere I have an article written a few years ago about the vehicle as then displayed. It seems to have had a number of unfortunate owners prior to becoming a museum exhibit, and was not in original condition, missing some of the instrumentation, and with incorrectly matched tyre sizes!
Yes, I have them stored and alos an ever-growing collection of pictures of the museum exhibit. I'm not a scratchbuilder (yet) but sure this one is in my "what if" folder.
Do you think that having a model of the thing could be of ill-luck as well? Maybe some minor disgrace, like missing a train, because the car is in a small scale?
The only model rendition of the automobile I'm aware of is an example from Yeomanry Miniatures(UK cottage industry) a couple years ago. It is in 1/32 scale however, and includes a number of figures.
