I'm so sorry about late answer, but I was really busy in the last month. Only the last week had time again to work on my beast and answer to your questions.
So the TPD-K1 has been fixed from another turret. I have a friend who actually sculpted the SBS turret, and that is correct as shape as size also. So he gave it to me a full turret, and I just cut out that. It's just can not credit for it

But If I'm here now I just drop few photos, to show, the topic has not died yet! I finished with the turret numbers, as you can see on original photo (I had to create my own stencils) and finally started to paint the chipping.
I hope you like it guys!






Cheers
