If you want a vintage look you need more than vintage lenses. Start with a film closer to what was available. Until about 1950 the fastest film generally available was Super XX with a Weston rating of 100. The most commonly available 35mm film during WWII was DuPont Superior #2 with a Weston Speed of 50. Efke 25 comes close to these in structure and speed. The curve will be more like DuPont because Super XX had a straight line curve which is not really approached today.
Vintage developers are another necessity - D-23,D-76, etc.
Papers are another story since cadmium and other chemicals common in the old papers are not allowed today. Best alternative would be hand coated POP.
