Thank you for helpful information. Sounds simple enought to screwed markings up? Three guys is very hard to find except on ebay some day... The aircraft I am looking to build are any one of these, 52-3531 or 57-2597 but lack of information of the other side of each aircraft. The first may be the most possible which also had something like reversed 'L' strip but I cant identify the wing badge which is not so clear, the second have the same problem. I dont know wing badge in Heller box is appropriate? I also look at XtradecalBoeing KC-135A Fin Bands and Badges if needed. Nice to know If someone say purpose of mentioned 'L' strip, why placed port side only and which wing badge placed on both aircraft or marking information for another specific U-Tapao KC-135?
