I've seen some cool old Stollenwerks ... Jeff of First Flight had one in his shop the last time I was in Statesville, and I think there's one on Aldo Ross's Photopoint album pages ... in fact, I think there's a Bauer there, too. Of course I'm too lazy to track down the URL ...
The Stollenwerks I have seen were all mid-50s or earlier, btw.
