The props that I got have no nut markings on them and have never been mounted. It doesn't mean that they weren't stolen. I just think it's suspicious that this guy has so many props and didn't mention it to me when I met him at a "convenient" place (not his house) to pick them up. The factory markings look normal to me. I hope they are OK, and I certainly hope that they are not stolen - I would have no way of knowing, props are not serialized. I suppose they could be fakes, but if so I won't know until I try them out.
