Maybe Velo-Orange is worth a look.
VO seems like a personable small company and maybe would answer email inquiries. They've got their own blog: http://velo-orange.blogspot.com/
Largely about what they are selling, but maybe they have additional information. I just scan it from time to time. They sell some nice products a Dutchman told me. Some things are expensive like their bicycle racks but the costs on those brake levers and some of their other items don't seem to be exorbitantly priced. Those Cane Creek bike levers have the QBP watermark in the enlarged picture. if there is a price difference, one could possibly go directly to QBP whom I assume the watermark is in reference to.
QBP ( meaning Quality Bicycle Products) http://harriscyclery.net/page.cfm?PageI ... =78&type=C
Catalog online might be of help too. A lot of bicycle shops carry QBP catalogs.
