Here's a couple pictures of the bracket "in action" as it were with my Huret Success Ti:

Note: this is one of the "fancy" brackets, with an angle adjusting screw; a non-adjustable version was also available. This was simply a slotted washer (to mate with tabs on the der body) with a bent tab at the proper location to hold the unit at the appropriate angle:
