TB-6 / ANT-26- any information? Any at all?

I was just curious if anyone had ANY information concerning the Russian Tupolev TB-6 (also known as the ANT-26) twelve engined bomber. I know a small glider version was built, but I would really like to see a picture of it.

I’m looking for visuals more than info, but anything would be good. Books, perhaps? Anything.

Thanks! [:D][tup]
