Kamov insanity!! Help W/ reference

Recently sidelined all my old projects (Again?!) In pursuit of my new addiction, Russian Helo's in 1/72. the Problem: Very little Reference photos! i've done pretty extensive research on the web, and come up with pretty decent exterior shots. My two projects right now are the Airfix Ka-25B and the Zvezda Ka-29 Gunship I'm badly in need of interior shots of both of these incredibly cool Choppers! I have both totally opened up in the hopes of doing the whole interior cargo/passenger bays and am hoping somebody out there came up with something I missed - Book suggestions would be great to - thoguh they seem even harder to come by - these choppers seem to be widely scattered all over the world- somebody musta taken a few photo's!
