Given the softness of the detail and the general poor quality of the mouldings, its doubtful they are from the original moulds. It was my understanding, from a similar discussion on another forum, that these were not licensed copies. Of course, that information might be wrong. KiTech doesn't have a website, so no way to contact them. If anyone out there has definitive info, I'm sure we'd all like to hear.
I too have limited funds for my hobby. I'm as cheap as the next guy, buying stuff on sale, cruising the dollar bins at the Nationals and local shows, waiting for the Squadron flyer. I also buy stuff from the local hobby store at full price on occasion, to help them stay in business a little longer. It helps salve my conscience a little. We do what we can. I personally would not knowingly buy a cheap knock off. But that's my choice. We are all different.
