here is an illustration for the Sachs/Huret braze-on front mech from the manufacturer's catalogue of 1985
unfortunately a part number for the braze-on is not given...
the ALGI 5.0mm X .8 screw (think "Christophe toeclip bolt") in the downtube is there as a "placeholder" to close off the hole for the mount point of a set of topmount shifters
cycle's apparent date of circa 1984 puts it in that brief time period when such shift lever sets were a trend
