Tanks for all who tried to help me. I've contacted with Germanischen Nationalmuseums, Nürnberg and got following answer:
Museum: "Dear Alexander, as the Tannenberg rifle is handmade, it isn't that easy to measure. The length differs between 318 and 320 mm, the diameter of the chamber between 15,9 up to 20 mm. The shape in general is cylindrical, but is has a partition in the middle. Please find a photo attached.
Spiridonov: "Thank You. So, As I understand the real shape inside hangonne is like on this picture variant A but not B"
Museum: "Yes, the shape inside the Tannenberg handgonne is closer to version A than version B. "
