While I don't collect ID models I do have something which may be of interest. The approximately 1/72 scale C-118/DC-6 in United Airlines livery came to me in a Cruver box. There are no manufacturer or ID markings on the belly that I can see. The story was that Cruver painted and decaled some transports in hopes of sparking demand for these old ID's after the war. Maybe someone can confirm that story. The paint is very light and thin while the waterslide decals are quite thick. The landing gear is very stout which is a good thing for a hefty model like this.
I would have included a pic of the box but it is stored in the box vault somewhere and it would take hours to find.
