This is an original Williams Brothers release and as such the molds are old and the kit has a great deal of molding flash. the instructions are very minimal, at times are contradictory, and show several model variants of the original aircraft y, but don't give any indication if these variations apply to any of the aircraft shown in the kit. Some parts have to be made or modified by the modeler. The decals take a long time release from the backing. Don't get impatient. If you try to brake them loose the will come part in small pieces. I found it's best to not install the small clear windows. Wait until after you paint the model and then fill the window openings with Elmer's White Glue. This will dry clear. This kit takes a lot of work, but can be made into a very nice model.
