Wow! That is a fabulous idea, and I really like the machine you are copying.
I guess I could use one of my Capo Sieger frames as the basis for a replica of the bike Adolf Christian rode to 3rd place in the 1958 TdF. I think his had Capo brand derailleurs, for which the old 1950s Simplex bandspring rear and rod-shift front would be reasonable stand-ins, and I would need low flange hubs with wingnuts, as well as sidepull brakes. I did find this picture of a 1952 Sieger, and his does not look a lot different, based on the two photos I have found. The components are embarrassingly primitive compared to the Campagnolo / Mafac mix on your project.
I also would not want to modify my frame for internal derailleur and brake cable routing, something Otto Cap evidently abandoned sometime during the 1950s.
