Small Scale Military Headquarters

I try to built the B25 (Flak bait) from Flying Styro. To give it a much better looking (in my opinion) I want to give here correct motor plates, detailed guns(4 complete and 12 time only the pipes) and the inside for the upper gun turret. For that I need a damaged Avenger. The second motor plate I need should be possible by casting. The guns from the first released american halftrack would maybe be useable. Who can help Would like to trade. Got several modern figures, tanks, vehicles, helos and a big amount of WW2 figures, tanks and planes for trading.
Thanks
