Hi Harlan, thanks for your answer. I tried to google the B-13 but without any succses is this , because of the B, a light bomber ? Also in my books i couldnt find it. Please be so kindly and lighten this black hole in my mind.

Thanks and best regards

I just checked this thread again and I'm so sorry for my typo Gunner.
Yes, It's a B'T'-13. (Basic Trainer)

The designations at time for trainers was:
PT - Primary Trainer
BT - Basic Trainer
AT - Advanced Trainer
