The Rolleipan 200 is very similar to Agfapan, which I always used to photograph WW2 battleships & submarines, because of delivering that same tonality. If that's the look you're going for, Rolleipan 200 would be the way to go. If you're searching for an earlier look, the Efke 25 & Efke 100 would be the way to go, processed in Rodinal.

Good luck, and congratulations on a fine camera.

I have a Leica IIIa, manufactured date 1935, coupled with the Summar 50/2 I regularly use Efke 25 with much success. It is a fun camera to use, I use it as much as my M2. Slow film is no problem for these old cameras, use it and enjoy it. Rolleijoe has the right idea, I also use Rodinal for development.
