Almost all French constructeur frames in larger sizes were shorter than tall. This allowed you to get the handlebars high enoug for comfort without resorting to riser stems or other trickery. For example, I usually ride a 60 cm seat tube with a 57.5 cm top tube.

The derailleurs aren't brazed on. Singer always brazed a little piece on the seat tube that attaches to the hinge of the Huret derailleur, and a little eyelet on the other side to which the bolt attaches. That replaces the front part of the derailleur clamp. Almost every Alex Singer from the 1970s onward has that system.

No epoxy, and the derailleur remains removable. It's just converted to a braze-on attachment by replicating the relevant parts of the clamp in steel and brazing them to the seat tube.
