Here's a photo of Jobst Brandt and his son Olaf in Affoltern a. Albis, Switzerland; about to depart on their 2001 Alps Tour. You can see that Jobst's pump is mounted behind the seat tube. The frame was built by Peter Johnson. <http://f1.pg.photos.yahoo.com/ph/olafbrandt/detail?.dir=/Alps+Tour+2001&.dn m=102-0207_IMG+(Medium).jpg>
