1/350 HMS Ultor (P53) Royal Navy Submarine: Length: 6.5", Width: 0.75" These models come already assembled and painted out of the box. There is nothing to do or needed other than take them out of the packaging and display them. These models are mostly made of metal with plastic parts added for details such as antennas, periscopes, rails, guns, etc. The overall coloring and the details are very interesting, there are many grill marks accurately painted along with embossed hatches and panels. These models come with a cutaway section that reveal interior details like piping, machinery and torpedoes. The cutaway section is limited to only one side of the model. The model comes attached to a display stand. The base of the stand measures 4.75 inches by 1.75 inches. The display stand has a metal strip that shows the name/type and year of the model. This is certainly not a toy. It will not last long if played with. The box is labeled as not recommended for children under 14.
