I just got this in the mail yesterday, AiM's CL-44D conversion. This is so one can convert the Mach II Britannia into a CL-44. I'm going to use my Airways Vac Form Britannia though, I'll see how it gets on.
You get four white metal props, four resin Tyne nacelles, four fuselage plug halves (front and rear plug), two swing tail hinges and one clear windshield. The instruction sheet is really good I thought (sorry no photo of that)
