I have plowed through all those pictures too.Somewhere I seem to recall seeing white light on top of the sonar pod.Also the port and starboard lights are in the sail,if I recall correctly,roughly in the first 1/3 section of the sail.
I have a pretty good running collection of pictures of russian boats.Even some sho nuff video of real russian submarines.
I am always interested in the unusual and hard-to-find info on the Alfa,Akula,Typhoon,Oscar,and the mysterious Begula.
If anybody has something off mainstream,I would love to see it.
Meanwhile,if you will e-mail me your adress,I will try to find that picture for you.
