Labels specialising in obscure WWII films from Japanese & Soviet perspective

[blurayisnice]

Hello all!

Is there a label or are there labels that specialize in lesser known (to the point of obscure) World War II movies from Japanese and Soviet perspective?

There is so much stuff out there that I'd like to see, but most of it is either difficult to get or there exists no release (that I know of).

Some examples:

Stalingrad (1990)
Liberation (Osvobozhdenie: Napravlenie glavnogo udara), (1971)
Moscow Strikes Back (Academy Award Winning Documentary, 1942)
Battle of Okinawa (Gekido no showashi: Okinawa kessen, 1971)
Japan's Longest Day (Nihon no ichiban nagai hi), (1967)
Fort Graveyard (Chi to suna), (1965)
Two Soldiers (Dva boytsa), (1943)
The Young Guard (Molodaya gvardiya), (1948)
Storm over the Pacific (Hawai Middowei daikaikûsen: Taiheiyô no arashi, 1960)
Italiani brava gente (1964)
Momotaro, Sacred Sailors (Momotarô: Umi no shinpei) (1945) (Animated Japanese propaganda film made in the last year of war).

Western-made hard-to-find:

Black Fox: The True Story of Adolf Hitler (Academy best Doc, 1962)
Genocide (1982)

And then there is less obscure stuff that I'd like to see restored, such as:

Prelude to War (1942)
The Battle of Midway (1942)
The Fighting Lady (1944)
Triump of the Will (Triumph des Willens), (1935)

And other war documentaries, like:

The Anderson Platoon (1967)

If there is not a label that specializes in this kind of stuff, what label would be the most suitable? Milestone Films maybe? Kino Lorber?

I understand this is a very specific niche, but I think there would be demand if someone was offering.
