Peruano-

That is a very well preserved late 70s or early 80s Bertin touring bike. The C 132 guess looks to be about right but the Vitus 172 main frame would be an upgrade. The ridged stay caps usually denote Durifort on Bertins of this period. Check the forks just below the crown on the inside of the fork blades. They will likely will be stamped either durifort/Durifort or v. 172 to identify the material. The number 58 stamping on the rear NDS dropout indicates the center to top frame size measurement. Often the serial would be right below the frame size stamping but sometimes, like yours, the serial (1978) is on the drive side dropout face like here. The bike is largely original in its livery and its equipment but it is likely missing a Bertin head badge style decal right in the middle if the seat tube panel between the world championship stripes bands. It is also possible the Andre Bertin would have appeared on the down tube. The 78 and 79 on the Normandy/Milremo hubs indicate production dates . The Rear Simplex looks to be a Simplex SX 410 T. https://velobase.com/ViewComponent.a...=108&AbsPos=77
The front would likely have been an SJ 104. https://velobase.com/ViewComponent.a...=113&AbsPos=29
