I have a pre war Torpado (actually my brother and I share this project) in its original finish and the bike has a shifter boss braze on for the Simplex shift lever and a braze on for the derailleur so no hanger is necessary - derailleur is Simplex Campione Del Mondo. The brake cable and derailleur cables are also internally routed. The bike has no light bracket. I have a documented history on this bike and restoration will follow soon as the patina is a little too much for me.
Actually, the older the bike the more braze-ons it may have. By the mid 1930's if not earlier French touring bikes had full braze-ons and often times internal cable routing. The Italians became scared of braze-ons and then for many years they were not used for racing bikes. Of course top end French touring bikes always had them (and/or internal cable routing).
Also, early front deraillieurs (30's through 50's) were often brazed on, regardless of whether or not cable or rod actuated.

\r?\n> In order of oldest to newest
\r?\n> Top of BB derailleur guides
\r?\n> Chainstay cable stop (perhaps these appeared at the same time as the top
\r?\n> of BB derailleur guides )
\r?\n> Shift lever stop
\r?\n> Shift lever bosses
\r?\n> Top tube brake cable guides
\r?\n> Bottom of BB derailleur guides
\r?\n> Brake cables routed through top tube
\r?\n> Inside seat stay chain hanger
\r?\n> Front derailleur mount (Are these too new for the CR timeline?)
\r?\n> What about lamp brackets on forks?
\r?\n> What about rear brake cable stops for centerpulls?
\r?\n> What about pump pegs?
