If you want a period look, the old "tear drop" shaped Wixom Bags look good, but are not overly functional (IMHO) for long distance hauling. The Hepco Becker bags (similar to Krausers) are my favorite for being spacious and easily detached. I have a set of old Bates Bags on one of my bikes....they are more of a permanent mount. When traveling I found a set of CL1200 Bag Liner Luggage which fit the Bates bags well.....and have a set of old period Krauser Bag Liner Luggage for my Hepco Becker Bags. On a third bike I use a set of soft luggage from Nelson-Rigg.
