I think it’s safe to say it’s pre-release and they’ll be polishing out the molds for the clear parts. Airfix is a mainstream manufacturor with an excellent track record over the past few years, no way they’d deliver it like that. Not so sure about the belts. Plastic is certian to be be thicker than photo-etch or fabric, but it seems to me that the Typhoon and F6F belts have looked a bit better than that.
